中文摘要：

综述了3类广泛应用的α/β复合成核剂对聚丙烯结晶动力学、结晶形态及宏观性能等方面影响的研究进展。总结了影响α/β复合成核剂调控聚丙烯结晶的主要因素在于两种成核剂的成核能力,具体表现为其成核聚丙烯结晶温度（TC）的高低：TC高的成核剂在聚丙烯结晶过程中起主导作用,TC低的成核剂基本不起成核作用,当两者的TC相接近时发生竞争成核。根据这一规律,找出了复合α、β两种成核剂的方法,并列举将其运用到调控聚丙烯的结晶过程中的实例。

英文摘要：

Three kinds of well studied α/β compounded nucleating agents（NAs）,phosphate/amide,sorbitol/amide,and phosphate/carboxylate were selected to investigate their influence on the crystallization kinetics,crystallization morphologies,and mechanical proprieties of isotactic polypropylene（iPP）.It can be summarized the key factor of affecting the α/β compounded NAs is the crystallization temperature（TC）.The NA with higher TC plays a leading role in the crystallization process.Competitive nucleation will occur when the difference of TC between two NAs is not pronounced.According to this rule,the optimization method for compounding α and β NAs can be developed.An example of adjusting the stiffness and toughness of isotactic polypropylene based on different of α/β compound nucleating agents was employed.
