摘要：

Diester and hydroxy ester monomers containing internal five-, six-, and seven-member acetal rings were prepared and converted into linear polyesters, copolyesters, and copolyamides. The polymers so obtained were characterized for glass temperature, crystallinity, melting point and ring structure. The poly(ester acetals) served as prepolymers for thermosetting polymers cross-linked by ring opening, acetal-interchange reactions with acid catalysts and catalyst-promoter combinations. The effects of acetal ring size, temperature, catalyst and promoter on rate and degree of cross-linking were evaluated. © 1969, American Chemical Society. All rights reserved.
