While many people use the term 'polymer' and 'plastic' interchangeably, polymers are a much larger class of molecules which includes plastics, plus many other materials, such as cellulose, amber, and natural rubber. low temperature polymers such as polyethylene and polypropylene.913 The low temperature used to melt these polymers during processing is able to avoid the degradation of the natural ber and additionally result in easier processing. The authors evaluate polymeric materials based on a synthetic polymer - polyethylene - as the most produced and natural polymers, such as natural rubber. As noted above, synthetic HDPE macromolecules have masses ranging from 10 5 to 10 6 amu (LDPE molecules are more than a hundred times smaller). Memory foam consists mainly of polyurethane with additional chemicals that increase its viscosity and density.It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam ().The foam bubbles or cells are open, effectively creating a matrix through which air can move. It is produced by linking ethylene molecules to a larger molecule that has a branched chain structure. PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimentation. Polyethylene, composed of repeating ethylene monomers, is an addition polymer. Photodegradation. Many simple hydrocarbons, such as ethylene and propylene, can be transformed into polymers by adding one monomer after another to the growing chain. Here are the natural mechanisms by which plastics can degrade: Physical degradation. Polythene is the simplest type of synthetic polymer.
