Abstract: Stabilized polyolefin molding materials comprising:- (1) a polyolefin; (2) a stabilizer; and optionally (3) one or more conventional other auxiliaries or additives and containing certain 4-(m,m''-ditert.-butyl-p-hydroxyphenyl)-butyl- (2) compounds as stabilizers. The polyolefins exhibit better stability than prior art stabilized polyolefins.
