초록

Useful hydroxyl-terminated polyolefin prepolymers, e.g. polybutadiene prepolymers, are provided which may be cross-linked with an epoxide to yield a polyether elastomeric material or with a mixture of an anhydride and an epoxide to form a polyester material. One such prepolymer is a carboxyl-terminated polyolefin, e.g. polybutadiene prepared by reacting a hydroxy-terminated polyolefin, e.g. polybutadiene with solid or liquid anhydrides. Polyether and polyester propellants containing up to about 88% of solid ammonium perchlorate in the powder form and alu...

청구항

A process for preparing a cross-linked elastomer which comprises: (A) preparing a carboxyl-terminated polyolefin by reacting a hydroxyl-terminated polyolefin selected from the group consisting of polypentadiene, polyheptadiene and polyisoprene, each having hydroxyl end groups, and polyethylene, polybutylene, and polypropylene, each having hydroxyl end groups, with an acid anhydride; and (B) reacting the carboxyl derivative so formed with an epoxide containing at least two epoxide groups in the presence of a metallic salt catalyst selected from the group ...
