Chapter 11. Applications and Processing of Polymers
Polymers play a very important role in human life. In fact, our body is made of lot of
polymers, e.g. Proteins, enzymes, etc. Other naturally occurring polymers like wood,
rubber, leather and silk are serving the humankind for many centuries now. Modern
scientific tools revolutionized the processing of polymers thus available synthetic
polymers like useful plastics, rubbers and fiber materials. As with other engineering
materials (metals and ceramics), the properties of polymers are related their constituent
structural elements and their arrangement. The suffix in polymer ‘mer’ is originated from
Greek word meros – which means part. The word polymer is thus coined to mean
material consisting of many parts/mers. Most of the polymers are basically organic
compounds, however they can be inorganic (e.g. silicones based on Si-O network). This
chapter introduces classification of polymers, processing and synthesis of polymers,
followed by mechanism of deformation and mechanical behavior of polymers.
11.1 Polymer types and Polymer synthesis processing
Polymers are classified in several ways – by how the molecules are synthesized, by their
molecular structure, or by their chemical family. For example, linear polymers consist of
long molecular chains, while the branched polymers consist of primary long chains and
secondary chains that
