Abstract
Abstract A polyolefin resin composition consisting essentially of at least one homopolymer of copolymer of an aliphatic monoolefin and 0.05 to 2% by weight, based on the weight of the composition, of a dibenzylidene sorbitol derivative of the following formula wherein R and R' are different from each other and each represents a member selected from the class consisting of a hydrogen atom, a chlorine atom, alkyl groups having 1 to 3 carbon atoms and alkoxy groups having a C 1 -C 3 alkyl moiety.
