AROMATIC POLYIMIDES DERIVED FROM AROMATIC DIANHYDRIDES AND CHLORINATED AROMATIC DIAMINES

摘要

PE-0146 TITLE AROMATIC POLYIMIDES DERIVED FROM AROMATIC DIANHYDRIDES AND CHLORINATED AROMATIC DIAMINES Aromatic homopolyimide and copolyimide films derived from an aromatic dianhydride and a chlorinated aromatic diamine such as 2-chloro-p-phenylene diamine and 2,2'-dichloro-4,4'-diaminodiphenyl ether are described. The films have low water absorption, high elastic modulus and elongation and can be heat-processed without embrittlement.
