Abstract

Three α/β compound nucleating agents based on 1,3,5-benzenetricarboxylic acid tris(cyclohexylamide) (BTA-99) were prepared by using β-nucleating agents aromatic diamides (TMB-5), dicarboxylic acid salts (CaPi) and rare earth compound (WBG-II), and nucleation effects of the nucleating agents in isotactic polypropylene (iPP) were investigated. The optimal ratio of BTA-99 to TMB-5, CaPi and WBG-II was 1:1, 4:1 and 2:3, respectively, and the crystallization peak temperatures of iPP nucleated with BTA-99/TMB-5, BTA-99/CaPi and BTA-99/WBG-II were increased from 117.7 °C of pure iPP to 129.7 °C, 127.6 °C and 128.9 °C under the optimal ratio, respectively. Moreover, all compound nucleating agents with the optimal compound ratio improved both the stiffness and the toughness of iPP, and TMB-5 was more suitable as a component for preparing compound nucleating agents with BTA-99 than WBG-II and CaPi. Meanwhile, an interesting phenomenon was found that the smaller the difference of the nucleation efficiency between two nucleating agents, the better the nucleation effect of the compound agent was.
