Polyurethane based on hydroxyl‐terminated polybutadienes

Abstract

Abstract Butadiene has been found to homopolymerise and copolymerise with other reactive vinyl monomers to yield unique liquid polymers which are terminated with reactive allylic hydroxyl groups. Through the use of an isocyanate cure reaction they offer a route to liquid castable general purpose elastomers, capable of reinforcement with various fillers and extension with a wide variety of low cost process oils.
