Kind Code:

A1

Abstract:

A hexagonal crystal of a diacetal of general formula (1) (wherein R1 and R2 are each C1-C4 alkyl or halogen; m and n are each an integer of 0 to 2; and p is 0 or 1); a nucleating agent comprising a diacetal of the above general formula (1), part or the whole of the molecules thereof being hexagonal crystals; a polyolefin resin composition comprising the nucleating agent and a polyolefin resin; an article molded from the resin composition; and a process for molding the resin composition. The present invention makes it possible to give molded articles free from fish-eye and discoloration and excellent in optical, mechanical and thermal properties in a shortened molding cycle.
