how are polymers important

Polyesters - Polymers with ester linkage are called polyeste..

The large scale use of synthetic polymers has been based on their relative inertness to environmental process so that degradation reactions leading to any change in the properties of the polymer during the service life of its product does not occur. It is due to this property th..

Polymer is a compound of high molecular mass formed by a combination of small molecules called monomer..

Introduction - Polymers are macro-sized molecules of relatively high molecular mass, which find extensive use in our daily life. Polymers are large but single chain-like molecules in which the repeating unit derived from small molecules called monomers are covalently linke..

Thermosetting polymers made from relatively low molecular mass semi-fluid polymers which when heated in a mould forms an insoluble hard mass which is infusible. This is due to extensive crosslinks between the different polymer chains forming three dimensional network ..

Addition polymers are formed when monomer units are separately added to form long chains without elimination of any by-product molecules. These polymers are formed by reactions between monomer molecules possessing multiple bonds. Example: Ethylene undergoes polymerization to fo..

Condensation polymers are formed when the monomers containing active functional groups (generally two), which react together with the elimination of a small molecule like water, ammonia, alcohol etc. Examples: Nylon-66, polyester, bakelite etc. Nylon-66 is formed by condensation between ..

Generally a polymer sample contains chains of varying lengths and therefore its molecular mass is always expressed as an average. In contrast, natural polymers such as proteins, contains chains of identical length and hence have definite molecular ma..
