摘要：

In order to prepare the zeolite filled beta-iPP composites, the calcium pimelate as beta-nucleator supported on the surface of zeolite (beta-zeolite) was prepared by the interaction between calcified zeolite and pimelic acid. The beta-nucleation, crystallization behavior and melting characteristic of zeolite, calcified zeolite and beta-zeolite filled iPP composites were investigated by differential scanning calorimetry and wide-angle X-ray diffractometer. The results indicated that addition of the zeolite and calcified zeolite as well as beta-zeolite increased the crystallization temperature of iPP. The zeolite and calcified zeolite filled iPP composites mainly crystallized in the alpha-crystal form and the strong beta-heterogeneous nucleation of beta-zeolite results in the formation of only beta-crystal in beta-zeolite filled iPP composites. The zeolite filled beta-iPP composites with high beta-crystal contents (above 0.90) can be easily obtained by adding beta-zeolite into iPP matrix. (C) 2012 Elsevier B.V. All rights reserved.
