A method for producing a polyolefin composition, which comprises melt-kneading a particulate composition (A) containing a compound represented by formula (1) :
wherein R1 represents an alkyl group having 1 to 8 carbon atoms, X represents an n-hydric alcohol residue having 1 to 18 carbon atoms which may include a heteroatom and/or a cyclic group, and n is the integer 2 or 4, and a metal soap, and a particulate polyolefin (B), wherein the ratio (a/b) of the average particle diameter (a) of the particulate composition (A) and the an average particle diameter (b) of the particulate polyolefin (B) is adjusted to 3/1 to 1/3, and wherein average particle diameter means the central cumulative value determined from a weight-based particle diameter cumulative distribution for residue on a sieve measured in accordance with JIS K 0069.
一种生产聚烯烃组合物的方法,包括熔融捏合含有由式(1)表示的化合物的颗粒组合物(A):
其中 R1 代表具有 1 至 8 个碳原子的烷基,X 代表具有 1 至 18 个碳原子的 n-水醇残基,其中可包括杂原子和/或环状基团,n 为整数 2 或 4,以及金属皂和微粒聚烯烃 (B)、其中,颗粒组合物(A)的平均颗粒直径(a)与颗粒聚烯烃(B)的平均颗粒直径(b)之比(a/b)调整为 3/1 至 1/3,平均颗粒直径是指根据 JIS K 0069 测量的基于重量的筛上残留物颗粒直径累积分布确定的中心累积值。
