Polypropylene （PP） has good market prospects due to its wide source of raw materials, low price, easy processing and good mechanical properties. However, large spherulite size, high embrittlement temperature, poor impact and other shortcomings limit its wide range of applications. At present, addition of nucleating agents into PP during processing is one of the most effective modification methods. As one of the earliest types of beta nucleating agents, aliphatic dicarboxylates have positive effect on the rigidity and surface hardness of PP ma...
