Multiple base propellant with combustion inhibitor
First Claim
1. A double base propellant charge having in intimate contact with at least a part of its surface an elastomeric sheath comprising about 30 parts by weight of a copolymer having dispersed therein about 70 parts by weight of a filler selected from polyoxymethylene and oxamide, said copolymer comprising about 70% by weight of units derived from ethylene, about 15% by weight of units derived from methacrylic acid and about 15 parts by weight of units derived from methyl methacrylate.
