Disclosed are, for example, a process for producing a tricarboxylic acid tris(alkyl-substituted cyclohexylamide), the process comprising subjecting a tricarboxylic acid and an alkyl-substituted cyclohexylamine to an amidation reaction, either (a) in the presence of a boric acid compound and a phenol compound or (b) in the presence of a boric acid ester obtained by the dehydration condensation of a boric acid compound and a phenol compound, and optionally purifying the resulting crude reaction product.

Process for producing tricarboxylic acid tris (alkyl-substituted cyclohexylamide)

Disclosed are a composition for controlling the crystallization rate of a polyolefin-based resin, the composition comprising (A) an amide-based compound which is a substituted or unsubstituted cyclohexylamide of 1,2,3-propanetricarboxylic acid or 1,2,3,4-butanetetracarboxylic acid and (B) a fatty acid metal salt, wherein the component (A):component (B) weight ratio is from 100:0 to 30:70; a method for controlling the crystallization rate of a polyolefin-based resin, comprising incorporating the composition into the polyolefin-based resin to obtain a polyolefin-based resin composition and molding the resin composition; molded products obtained by the method; and the like.

Method and composition for control of crystallization rate of polyolefin resin, resin composition and resin molding

Disclosed are a mixture of at least two amide-based compounds represented by General Formula (1): wherein a represents an integer of 2 to 6, Rrepresents a Csaturated or unsaturated aliphatic polycarboxylic acid residue, and the aliphatic polycarboxylic acid has a valency of 2 to 6, and two to six Rgroups are the same or different, and each represent a trans-2-alkylcyclohexylamine residue or a cis-2-alkylcyclohexylamine residue, the mixture having a content of a trans-2-alkylcyclohexylamine residue of at least 70 mole % but less than 100 mole % of the total 2-alkylcyclohexylamine residues in the mixture, or an all-trans amide-based compound wherein all of the 2 to 6 Rgroups represent a trans-2-alkylcyclohexylamine residue; a polyolefin resin nucleating agent comprising the mixture or the all-trans amide-based compound; a polyolefin resin composition containing the amide-based compound or the mixture; a molded article obtainable by molding the composition.
