Abstract
A diblock copolymer based on poly(p-benzamide) (PBA) and poly(2-phenyl ene-(5-benzimidazole))isophthalamide (PABI) was synthesized by direct coupling reaction between acylchloride and amino end groups of the two homopolymers. Soxhlet extraction with N,N'-dimethylacetamide complete ly removed unreacted PABI and allowed determination of copolymer conte nt and composition of the unextracted fraction (by u.v. data and visco sity measurements). Preliminary results on phase behaviour are given a nd analysed in terms of block length.
