Disclosed are a mixture of at least two amide-based compounds represented by General Formula (1):
R1― (CONH R2)a (1)
wherein a represents an integer of 2 to 6, R1 represents a C2-30 saturated or unsaturated aliphatic polycarboxylic acid residue, and the aliphatic polycarboxylic acid has a valency of 2 to 6, and two to six R2 groups 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 R2 groups 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.
本发明公开了至少两种由通式(1)表示的酰胺基化合物的混合物:
R1- (CONH R2)a (1)
其中 a 代表 2 至 6 的整数,R1 代表 C2-30 饱和或不饱和脂肪族多羧酸残基,脂肪族多羧酸的化合价为 2 至 6,2 至 6 个 R2 基团相同或不同,且各代表反式-2-烷基环己胺残基或顺式-2-烷基环己胺残基、该混合物中反式-2-烷基环己胺残基的含量至少占混合物中 2-烷基环己胺残基总量的 70 摩尔%,但小于 100 摩尔%,或全反式酰胺基化合物,其中所有 2 至 6 个 R2 基团均代表反式-2-烷基环己胺残基;包含该混合物或全反式酰胺基化合物的聚烯烃树脂成核剂; 包含该酰胺基化合物或该混合物的聚烯烃树脂组合物; 可通过模塑该组合物获得的模塑制品。
