研究了1，3，5-苯三甲酸三(环己胺)(BTCA-TCHA)成核剂的添加量对聚丙烯(PP)拉伸性能、弯曲性能、雾度以及结晶峰温度的影响，并与高效的商用二苄叉山梨醇类成核剂Millad 3988进行了比较。结果表明，成核剂BTCA-TCHA在较低的添加量(质量分数为0.20%左右)就具有非常优异的成核效果。当BTCA-TCHA质量分数为0.2%时，PP的拉伸强度和弯曲弹性模量可分别从纯PP的30.85 MPa和1530 MPa提高到33.85 MPa和1720 MPa(分别提高9.73%和12.42%)，雾度可从空白PP的80.12%降低到37.25%，降低幅度为53.51%，而冷却速率为20℃/min时其结晶峰温度可比纯PP提高12℃左右，其成核效果与Millad 3988类似。此外，BTCA-TCHA在PP中的添加量存在一饱和值(质量分数为0.2%)，当添加量超过该值以后，继续添加成核剂对PP性能的改善效果不明显。

Effects of addition amount of nucleating agent 1,3,5-benzenetricarboxylic acid tris(cyclohexylamide)(BTCA-TCHA) on tensile,flexural and optical properties as well as crystallization peak temperature of polypropylene(PP) were investigated and the results were compared with those of PP nucleated with a highly effective commercial nucleating agent Millad 3988. The results show that BTCA-TCHA have good nucleation effects at very low addition amount(mass fraction about 0.20%). When the mass fraction of BTCA-TCHA in PP is 0.2%,tensile strength and flexural modulus of PP increase from 30.85 MPa and 1530 MPa of pure PP to 33.85 MPa and 1720 MPa(increased by 9.73%and 12.42%),respectively,and the haze value of PP decreases from 80.12%of pure PP to 37.25%(decreased by 53.51%). The crystallization peak temperature of PP at the cooling rate of 20℃/min increases by about 12 ℃ when compares to that of pure PP. It is found from comparison on nucleation effects of BTCA-TCHA and Millad 3988 that the nucleation efficiency of BTCA-TCHA is similar to that of Millad 3988 with high nucleation efficiency. In addition,a saturation value(mass fraction 0.2%) exists for the addition amount of BTCA-TCHA in PP. When the addition amount of BTCA-TCHA exceeds the value, the effect of improving PP performance through continuing adding BTCA-TCHA is not obvious.
