摘　　要：The effects of type and amount of chain extenders, hydroxyl terminated polybutadiene(HTPB) of different molecular weights and filler on the hydrolytic stability of polybutadiene based polyurethane elastomer were studied. The results showed that the stability of HTPB PU was improved by addition of chain extenders, especially butanediol and 1,6 hexanediol. The more the amount of the extender, and the lower the molecular weight of HTPB, the higher the hydrolytic stability. The stability of HTPB PU could be improved also by addition of inorganic fillers.The effects of type and amount of chain extenders, hydroxyl terminated polybutadiene(HTPB) of different molecular weights and filler on the hydrolytic stability of polybutadiene based polyurethane elastomer were studied.
