ABSTRACT:
Binders for propellants for the like comprise elastomers which are based on block copolymers in which a pair of poly(caprolactone) blocks flank a central hydroxyl-terminated poly(butadiene) block. The block polymers are cured with isocyanates through the OH termini of the poly(caprolactone) blocks. The elastomers have inherent energies and other characteristics intermediate those of PCP and HTPB and have good compatibility with nitrate ester plasticizers.
