Segmented thermoplastic copolyesters |
摘要 |
This invention relates to polyester polyether segmented copolymers wherein the polyether segment contains a certain amount of heterocyclic ring repeat units, for example, the hydantoin ring. These polyester polyether segmented copolymers are useful in the production of fibers, films or other extrusion moldings where elastomeric properties are desirable.
