摘要
Hydrolysis of solution-grown crystals and X-ray crystal structures were investigated in some Copolyesters. The isomorphism of the copolymers is discussed. The folded-chain crystals of the solution-grown crystals are changed to extended-chain crystals by hydrolysis. The changes of the counit content indicate that ethylene is-ophthalate units can coexist, but ethylene orthophthalate and sebacate units can coexist only to a limited extent, with ethylene terephthalate units in the central portions of the lamellae. These results agree well with the X-ray studies of the fiber structures. Two types of constitution diagrams are proposed for the copolymer. © 1969, Taylor & Francis Group, LLC. All rights reserved.
