COPOLYMERIZATION OF CYCLIC ESTER OLIGOMERS

摘要

Chemically different cyclic ester oligomers can be copolymerized to form copolyesters whose properties can be tailored by the choice of cyclic ester oligomers used. The copolyesters formed are especially useful as encapsulant s and as coatings. In many instances the copolyesters, assuming they are not randomized in later transesterification reactions, have unique microstructur es related to the sequencing of repeat units the their polymer chains.
