Polyurethane Elastomers Based on Hydroxyl-Terminated Polyurethane

Abstract

Polyurethane elastomers prepared from hydroxyl-terminated polybutadiene polymers and copolymers have been assessed and compared with polyester and polyether urethanes. The effects of various diols and diamines as chain extenders and crosslinking agents and additions of carbon black to the hydroxyl-terminated polybutadienes have also been studied. Hydroxyl-terminated polybutadiene urethane elastomers showed superior hydrolytic stability to the polyester and polyether urethanes selected for comparison; on the other hand, their resistance to petroleum (STF) was less satisfactory.
