Abstract:

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 reference value for the development and performance optimization of new coal based polypropylene products.

Key words: coal-based polypropylene, Innovene gas phase process, hydrogen-regulating method, high melt index
