Thermoplastic copolyester elastomers (TPE-E or COPE) are block copolymers. The chemical structure of one such elastomer is shown in Fig. 10.2. 

General Description Amitel is DSM Engineering Plastics family of copolyesters (COPEs) and thermoplastic elastomers (TPEs). These resins are multiblock copolymers in which butylene terapthalate hard segments andpoly(alkylene oxide) soft segments alternate repeatedly along the polymer backboned 1... 

It must be appreciated that both standard and non-standard abbreviations are used. Often materials appear, and become used, before the standards committee has issued its suggestion. By this time a non standard abbreviation has become established or more than one abbreviation may appear for the same material. The thermoplastic elastomer, known as polyether ester elastomer, may be referred to as PEEL or, as COPE (from copolyester) or, as TEEE (thermoplastic elastomer ether ester) or, as YBPO (an American suggestion). 

Thermoplastic elastomers (TPEs), which combine the characteristics of both thermoplastics and elastomers, can be classified into two major groups. The first is made up of block copolymers formed by polymerizing a thermoplastic monomer with an elastomer comonomer, as in the case of styrene block copolymers such as styrene-ethylene-butadiene-styrene (SEBS). Engineering TPEs such as thermoplastic urethanes (TPUs), copolyesters (COPEs) and polyether block amides (PEBAs) can be included in this first group. Other types of copolymer are from the polyolefin family, consisting of the polyolefin...
