Abstract

The preparation of acid chloride of poly (propylene oxide) , PPO, the synthesis of prepolymer poly (p-benzamide), and of block copolymers of poly (p-benzamide)-b-poly (propylene oxide) are reported. The preparation of prepolymer poly (p-benzamide) , PBA, and activated PPO, as well as PBA-PPO block copolymer are discussed according to their FTIR spectra.
