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.
