摘　　要：采用Innovene气相工艺在国内某聚丙烯生产装置上成功开发出煤基高流动抗冲共聚聚丙烯,同时对开发的高分子材料开展了有机磷酸盐类成核剂改性研究,结果表明,CH-39、FT-21、TMP-6三类成核剂均能有效促进材料的结晶过程,提高其结晶速率,TMP-6改性后聚丙烯的弯曲模量稍低于其他3种成核剂改性的聚丙烯,CH-39、FT-21分别改性后的煤基抗冲共聚聚丙烯在拉伸性能、弯曲性能以及冲击强度方面性能基本一致,这为煤基聚丙烯新产品的开发和性能优化提供一定的工业参考价值。In this paper,The coal based high flow impact copolymerized polypropylene was successfully developed on a domestic polypropylene production unit using Innovene gas-phase process.At the same time,the modification of organic phosphate nucleating agents for the developed polymer materials was studied.The results showed that CH-39,FT-21 and TMP-6 nucleating agents can effectively promote the crystallization process and improve the crystallization rate of the materials,The bending modulus of TMP-6 modified polypropylene is slightly lower than that of polypropylene modified by other three nucleating agents,and the coal based impact copolymerized polypropylene modified by CH-39 and FT-21 is basically the same in tensile properties,bending properties and impact strength,which provides a certain industrial ref-erence value for the development and performance optimization of new coal based polypropylene products.
