CARBOXYL-TERMINATED POLYHYDROCARBONS

Abstract

Procedures were developed for the preparation of one pound lots of carboxylterminated polybutadiene (CTPB) by free radical polymerization using two different initiators. Several samples of varying molecular weights were prepared for further evaluation as propellant binders. Several initiator systems for the preparation of CTPB by anionic methods were investigated. The effects of a number of polymerization parameters were determined using a dilithiopolyisoprene initiator. Problems were encountered in the determination of solution viscosities and molecular weights of CTPB. Evidence was obtained for association of CTPB in solution and gel permeation chromatography produced some anomalous results.
