摘要:
This invention provides a thermoplastic resin composition comprising a thermoplastic resin and 0.1 to 100 parts by weight, per 100 parts by weight of the thermoplastic resin, of an imide compound prepared, e.g., by dehydration condensation of 1,2,3,4-butanetetracarboxylic acid or a monoanhydride or a dianhydride thereof with a primary amine, and a method of molding the resin composition.
摘要:
This invention provides a granular or powdery diacetal composition comprising: (a) at least one diacetal such as 1,3:2,4-O-dibenzylidene-D-sorbitol or a nucleus-substituted derivative thereof, and (b) at least one binder selected from the group consisting of neutral or weakly acidic monovalent organic acids, neutral or weakly acidic polyvalent organic acids, partial salts of neutral or weakly acidic polyvalent organic acids, salts of sulfuric acid ester, sulfonic acid salts, salts of phosphoric acid ester, phosphoric acid esters, phosphorous acid esters and aluminum salts of a neutral or weakly acidic monovalent organic acid, the binder being uniformly dispersed on the surface and in the interior of the particles of the granular or powdery diacetal composition; a process for preparing the composition; a polyolefin resin nucleating agent comprising the composition; a resin composition containing the nucleating agent and a polyolefin resin; and a polyolefin resin molded article.
