The synthesis and characteristics of poly(ester-ester) multiblock copolymers from DMT, alkyl glycols (C2-C10), and pivalolactone have also been described [36,37]. More details about the exchange of units between chains or segments in polymer systems, i.e., the type of the sequential order in condensation copolymers, were given by Fakirov and Denchev [185]. Roslaniec et al described the synthesis and physical properties of PEE containing aliphatic polycarbonate soft segments [38,40,41]. Multiblock copolyesters can also be obtained by an 

PTMO-D,L-lactide block copolymers have similar physical properties [89]. Very interesting are the chemical structure and the synthesis of a poly(ester-carbonate) multiblock copolymer based on poly(lactic-glycolic acid) and PCL segments [188]. The carbonate group was used as the end-linking element of two different polyester segments.

The multiblock copolymers of poly(alkylene terephthalate) with telechelic amine-terminated poly(butadiene-co-acrylonitryle) rubber (ATBN) are also very interesting [61-63]. The copolymer based on poly(pentamethylene tere-

Besides the thermoplastic elastomers based on poly(styrene-6-elastomer- -styrene) block copolymers, five others are of commercial importance polyurethane/elastomer block copolymers, polyester/elastomer block copolymers, polyamide/elastomer block copolymers, polyolefin block copolymers, and polyetherimide/polysiloxane block copolymers. All five have the multiblock A-B-A-B. structure. The morphology of the polyurethane, polyester,...
