Morphology, crystallization and dynamical mechanical behavior of iPP/nano-CaCO3 Composites

摘要：

　　This article studied crystallization behavior of nano-CaCO3 filled polypropylene under nonisothermal from the melt by differential scanning calorimetry(DSC).Morphology observation indicated with increasing CaCO3 content the aggregates increased.Nano-CaCO3 acted as nucleating site during nonisothermal crystallization in all iPP/nano-CaCO3 composites.For nonisothermal crystallization kinetic studies,the result indicated that the Jeziomy and Ozawa approach cannot adequately describe the nonisothermal crystallization kinetic of iPP composite.In addition,Mo equation was employed to describe the nonisothermal crystallization kinetic process with satisfied results.Dynamic mechanical analysis indicated with increasing CaCO3 content the glass transition decreased slightly.
