✦ Synopsis

Abstract

Slightly modified conventional techniques were successfully applied to prepare aliphatic benzoxazolediamines and the corresponding high molecular weight polyamides, which could be spun into excellent fibers. Compared to regular aliphatic polyamides, these products showed higher transition temperatures, improved thermal and light stability, and increased affinity for acid dyes. In additionβ€”quite unexpectedlyβ€”these fibers were highly crystalline and oriented after drawing at elevated temperatures.
