摘要
研究微量润滑剂对聚丙烯流变性能、结晶性能及热稳定性能的影响,结果表明:小分子润滑剂的添加明显改善了聚丙烯的流变行为,提高了熔体的流动性,而并未明显影响其热稳定性,两种润滑剂对聚丙烯结晶行为的影响不同。
The rheological properties, crystallization behaviors and thermal stability of polypropylene （PP） with a minor addition of lubricants were researched. The results showed that the theological performance were improved dramatically and the flow property became better because of the addition of lubricants with small molecular weight. The thermal stability were not affected significantly. The influence on crystallization of the two lubricants was different.
