摘要： A nucleating agent containing a phosphoric acid aromatic ester metal salt represented by formula (I) and having an average major-axis length of 10 µm or less, an average aspect ratio of 10 or less, and a bulk specific gravity of 0.1 or more:
(wherein R 1 represents C4-C8 alkyl group, R 2 represents hydrogen or C1-C8 alkyl group, R 3 represents C1-C4 alkylidene group, A is a metal having a valence of n, and n is an integer of 1 or 2). The nucleating agent exhibits excellent handling property when incorporated into a resin, and is highly effective in improving transparency and mechanical strength of the resin containing the agent.摘要翻译： 一种含有式（I）表示的平均长轴长度为10μm以下，平均纵横比为10以下，体积比重为0.1以上的磷酸芳香族酯金属盐的成核剂 ：
（其中R 1表示C 4 -C 8烷基，R 2表示氢或C 1 -C 8烷基，R 3表示C 1 -C 4亚烷基，A是价数n的金属 ，n为1或2的整数）。 当成核剂在结合到树脂中时表现出优异的处理性能，并且在提高含有该试剂的树脂的透明度和机械强度方面是非常有效的。 -

摘要： A nucleating agent which comprises an aromatic phosphoric ester metal salt represented by general formula (I) and has an average major-axis length of 10 mu m or shorter, an average aspect ratio of 10 or lower, and a bulk specific gravity of 0.1 or higher. It has excellent handleability in incorporation into resins, and is highly effective in improving the transparency and mechanical strength of the resins containing it. (In the formula, R represents C4-8 alkyl; R represents hydrogen or C1-8 alkyl; R represents C1-4 alkylidene; A is a metal having a valence of n; and n is an integer of 1 or 2.)
