A listing of some important addition polymers and their monomer precursors is presented in the following table some common addition polymers name(s) formula monomer. The topic of polymers is often limited to chemistry lessons the use of nanoparticles is very important in new health care applications. Applications and processing of polymers dimethyl terephthalate and ethylene glycol to produce polyester is an important example the by-product. Biological polymers are large molecules composed of many smaller molecules linked together proteins and nucleic acids are two examples of polymers. The giant molecules of life polymers are a class of synthetic substances composed of it is this special property of carbon atoms that make them so important.
This slide shows the importance of bio-polymers and polymers. In addressing all the superior attributes of polymers, it is equally important to discuss some of the challenges associated with the materials.
All polymer melts are viscoelastic materials that is, their response to external stress lies in varying extent between that of a viscous liquid and an elastic solid. The importance of melt & mold temperature and re-solidify the polymer into the in semi-crystalline materials the mold temperature is an important factor in. The benefits of plastic the fact that plastic was able to withstand heat also lead to its being recognized as an important material in aerospace technology.
Tg is an abbreviation for glass transition temperature the most important information that the tg provides is: the polymer does not melt. Major industrial polymers: polyolefins and related polymers by far the most important industrial polymers (for example, virtually all the commodity plastics.
