Diacetal composition, polyolefin nucleating agent comprising the diacetal composition, polyolefin resin compositions containing the diacetal composition, method for manufacturing the resin composition, and moldings

摘要

Disclosed are a granular or powdery diacetal composition comprising (A) a diacetal such as 1,3:2,4-O-dibenzylidene-D-sorbitol, (B) a sulfuric ester salt and (C) an aliphatic monocarboxylic acid, components (B) and (C) being uniformly dispersed in the particles of the granular or powdery diacetal composition, and component (B) being present in a proportion of 0.1 to 3 wt% and component (C) being present in a proportion of 0.3 to 5 wt%, and the total amount of component (B) and component (C) being not more than 7 wt%, based on the diacetal composition; a polyolefin resin composition comprising the diacetal composition and a polyolefin resin; a process for preparing the resin composition; and a molding prepared by molding the polyolefin resin composition.
