Crystallizable Polyetherimides, Method of Manufacture, and Articles Derived Therefrom

摘要

A composition is described, which comprises a crystallizable polyetherimide derived from the polymerization of: (a) a dianhydride component, comprising more than 96.8 mole % of 4,4′-bisphenol A dianhydride or a chemical equivalent thereof; and (b) a diamine component comprising a diamine or a chemical equivalent thereof, wherein the crystallizable polyetherimide has a Tm ranging from 250° C. to 400° C. and the difference between the Tm and Tg of the composition is more than 50° C. Further described are articles, such as fibers, made from the composition, methods for making the composition, methods for making the articles, and methods for using the articles.
