Unformatted text preview: It is possible to obtain a crosslinked polymer in a desirable shape by moulding methods. This is accomplished by carrying out the shaping operations before crosslinking occurs. Two types of intermediates include (i) linear polymers containing reactive sites and (ii) low molecular weight polyfunctional molecules (oligomers) * Polymer Terminology Polymer nomenclature has been largely a matter of custom without any one system being universally accepted. Three nomenclature systems that have been used are based on (i) source (monomer(s) used in its synthesis) poly(ethylene) poly(styrene) poly(vinyl chloride) poly(6-aminocaproic acid) poly(ethylene-co-styrene) poly(ethylene-ter-propylene-ter-1,4-hexadiene) (ii) polymer structure (iii) trade name...
