PROCESS FOR PREPARING A BLOCK COPOLYMER FROM POLYIMIDES AND USE OF THE BLOCK COPOLYMER FOR PRODUCING POWDERS AND MOULDINGS

摘要

The invention describes a process for preparing pulverulent polyimide-polyimide block copolymers. The result polyimide-polyimide block copolymers and compounds produced using them can be compressed into moldings by the direct forming method or by the hot compression molding method. Polymeric moldings can be produced therefrom by customary mechanical and thermal machining and forming methods.
