【Abstract】 In this paper, the working principle of polypropylene(PP) nucleating agent was reviewed, and the molecular structure of common carboxylic acids and their salt nucleating agents was classified. Meanwhile, the modification effect of each nucleating agent was introduced. In addition, the methods for improving the performance of such nucleating agents were also proposed, which provides some ideas for the subsequent research and development of carboxylate nucleating agents.更多还原
