Polyester copolymer
Webpolyester, any of a class of organic substances composed of large linear (chainlike) or cross-linked (network) molecules, or polymers, formed from a large number of smaller molecules, or monomers, by establishment of ester linkages between them. Polyesters most commonly are prepared from equivalent amounts of glycols (organic compounds … WebPolyesters are long chain synthetic polymers that have ester linkages. Polyester materials are used as fibers, plastics, and films; in composites and elastomers; and as coatings. They are truly versatile materials. In the late 1920s American chemist Wallace Carothers and his research group at DuPont began to investigate the formation of ...
