ABSTRACT:
Composite carboxy terminated polybutadiene (CTPB) rubber base propellants, in which the CTPB inherently contains 2,2'-methylene-bis(4-methyl-6-tert-butyl)phenol (A0-2246) added during CTPB manufacture and antagonistic toward conventional antioxidants added to the CTPB propellant, are provided, which contain a synergistic (see Markush definition) antioxidant mixture highly compatible with the inherently present AO-2246. Invention also provides the antioxidant mixture per se.
