聚丙烯——增塑剂共混体系结晶动力学的研究

Study on the Crystallization of Plasticizer-lsotactic Polypropylene Blends

PP与低粘度锭子油共混可得到高抗冲PP。用DSC法研究了等温和非等温结晶动力学参数。试验结果表明,锭子油与PP无定型分子具有相容性,它的加入可促进PP的结晶。

PP and low-viscosity hydrocarbon oil were blended to obtain highimpact PP.Parameters of isothermal and non-isothermal crystallization kinetiecs were studied by means of DSC technique. Results show that the hydrocarbon oil is compatible with amorphous region of iso-PP, and the addition of hydrocarbon oil can promote crystallization of PP.
