Effect of different types of external electron donors on hydrogen sensitivity of Ziegler-Natta catalysts
Based on the INNOVENE gas phase polypropylene production technology of Yan'an Energy chemical and co.LTD,by studying the production of homopolymer,random copolymer and impact copolymer with different melting index,and analysed influence of different external electron donors such as diisobutyldimethoxysilane,diisopropyl dimethoxysilane and tetraethoxysilane on the hydrogen sensitivity of Ziegler-Natta catalyst,A simple and easy mathematical formula is established to quickly estimate the molar concentration ratio of hydrogen to propylene in reactor corresponding to different product melting index,which provides theoretical and technical basis for producing other products with different melting index.
