摘要：

A series of metal salts of 7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid were synthesized, and their nucleation efficiency in isotactic polypropylene (iPP) was investigated. The results showed that potassium 7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylate (OBCHE19) is an effective -nucleating agent. Then, the effect of OBCHE19 concentration on the relative content of -crystals (K) and mechanical properties of iPP was investigated. The results indicated that the maximum K reached 0.82 and impact strength increased by 125% compared to that of pure iPP when the content of OBCHE19 is 0.1mass%. Furthermore, the non-isothermal crystallization kinetics and crystallization activation energy were investigated by the Caze method and Kissinger method, respectively.
