What is a polymer

The term polymer is commonly used in the plastics and composites industry, often as a synonym for plastic or resin. Actually, polymers include a range of materials with a variety of properties. They are found in common household goods, in clothing and toys, in construction materials and insulation, and in numerous other products Polymers are materials made of long, repeating chains of molecules. There are natural and synthetic polymers, including proteins and rubber, and glass and epoxies Polymer, any of a class of natural or synthetic substances composed of very large molecules that are multiples of simpler chemical units. Polymers make up many of the materials in living organisms, and they constitute the basis of certain minerals and human-made materials, such as paper and plastics Polymerer är kemiska föreningar som består av mycket långa kedjor byggda av upprepade mindre enheter, monomerer. Polymerkedjor skiljer sig från andra kedjemolekyler inom den organiska kemin därför att de är mycket längre än exempelvis kedjorna i alkoholer eller organiska syror. Reaktionen som sker när monomererna blir en polymer kallas polymerisation. Polymerer i form av konstruktionsmaterial kallas i dagligt tal för plaster. Med plaster menas emellertid. Polymer molecule A molecule that contains a sequence of at least 3 monomer units, which are covalently bound to at least one other monomer unit or other reactant (i.e. '3+1' rule). Other reactan

  1. A polymer is a complex grouping of molecules. These are also known as repeating units. Polymers form a three-dimensional network - going side to side, back to front, and up and down. They are linked together through a chemical bond. As these individual strands of molecules link together, they build something else
  2. gly limitless range of characteristics and colors. Polymers have many inherent properties that can be further enhanced by a wide range of additives to broaden their uses and applications. Polymers can be made to mimic cotton, silk, and wool fibers; porcelain and marble; and alu
  3. Polymers are lengthy chain compounds composed of monomers. A monomer is a molecule that can be bonded to other identical molecules. Polymers are basically enormous molecules made with a massive amount of smaller, identical molecules
  4. Polymers are often formed from crude oil however more recently polymers have been created from corn starch and vegetable fats to form Bioplastics. Polymerisation is the chemical process of monomers joining together to form polymers, often it takes many thousands of monomers to make a single polymer. 2 types of polymerisation reactions are listed below
  5. A polymer is a substance whose molecules have high molar masses and are composed of a large number of repeating units. Polymers can be both natural and synthetic. Polymers have a range of applications that far exceed that of any other class of material available

Polymer is composed of an outer impregnable layer preventing the loss of active substances and an inner polymeric layer functioning as a controlling membrane. The polymer matrix is designed based on the active substance used for the patch formulation, adhesion-cohesion balance, compatibility, and stability with other components of the patch [35] A polymer is a molecule made up of a chain of repeating units which are chemically bonded together. Adhesives are substances which are used to glue things together. A polymer adhesive is a synthetic bonding substance made from polymers and is considered to be stronger, more flexible and have greater impact resistance than other forms of adhesives A lithium polymer battery, or more correctly lithium-ion polymer battery, is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, such as mobile devices, radio-controlled aircraft and some electric vehicles What is it about them that makes polymers such a diverse group of materials?... Polymers are everywhere. They can be hard, soft, brittle, fluid and even bouncy

Everything you need to know about polymers!Polymers are large molecules made up of lots of repeating units called monomers. This video covers: how to identif.. By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for many parts. Each of those parts is scientists call a monomer (which in Greek means one part). Think of a polymer as a chain, with each of its links a monomer Anne Marie Helmenstine, Ph.D. Updated September 09, 2019. A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Polymers usually have high melting and boiling points. Because the molecules consist of many monomers, polymers tend to have high molecular masses

In less than 100 seconds, Peter Barham describes the science of molecular chains. Visit physicsworld.com for more videos, webinars and podcasts.http://physic.. When polymers are categorized depending on their molecular forces, there are three groups as thermoplastic polymers, thermosetting polymers, and elastomers. The main difference between polymer and elastomer is that a polymer is any large molecule built with small units called monomers whereas an elastomer is a special type of polymer which has elastic property A linear polymer is made up of one molecule after another, hooked together in a long chain. This chain is called the backbone. Now, linear polymers don't have to be in a straight, rigid line. Those single bonds between atoms in the backbone can swivel around a bit, kinda like paper clips hooked together end-to-end A polymer is a molecule, made from joining together many small molecules called monomers.The word polymer can be broken down into poly (meaning many in Greek) and mer (meaning unit). This shows how the chemical composition of a polymer consists of many smaller units (monomers) bonded together into a larger molecule.A chemical reaction bonding monomers together to make a polymer is.

Nucleic acid polymers are identified along the chain by the acidic character of each group. Cytosine, guanine and adenine are present in both RNA and DNA. Uracil is only present in RNA and is switched with thymine. The sugar present in these chains dictate its identity. A DNA molecule contains deoxyribose, while RNA is made with ribose For polymers with alternating double and single bonds, which was doped, has a movement of charge in the chain by resonance resulting in conductivity. Draw the band structure of a polymer and a conductive polymer. Discuss what results this difference. Figure 9 - Comparison of the Band Structure of a Common Polymer and a Conductive Polymer The polymer active sites are inside the matrix so the rate of action is largely dependent on the rate of diffusion through the polymer. Polymer must be used in solvents that will allow it to swell (DCM, THF, CHCl3). This also means that product can get trapped inside the polymer, greatly affecting the yield The polymer end--robbed of its hydrogen--easily forms a double bond with its adjacent carbon atom, and polymerization stops. Because every part of the ethylene monomer is included in the. Polymer chemists sometimes refer to the threshold molecular weight below which an oligomer will not display the properties needed for a particular application. The value of the threshold molecular weight depends on the application. If the polymer is to be used as an adhesive, the required molecular weight may be relatively low
