Manufacturing method of 2 mountain die polyolefine which use the metallocene catalytic converter which uses 2 reaction zones

摘要

(57) Abstract Being manufacturing method of the polyolefine which possesses the molecular weight distribution of 2 mountain dies (bimodal) or poly mountain dies (multimodal), in the (i) 1st reaction zone, under 1st polymerization condition olefin monomer and making also the 1st reaction raw materials contact with catalytic converter system, including the 1st polyolefine which possesses 1st molecular weight distribution, it produces the product which becomes; And in the (ii) 2nd reaction zone, under 2nd polymerization condition olefin monomer and making also the 2nd reaction raw materials contact with catalytic converter system, 1st molecular weight distribution including the fact that it produces the 2nd polyolefine which possesses the dyad quantitative distribution which differs, it becomes; The 1st and 2nd polyolefine is mixed together here, also one of the reaction raw materials is hydrogen, and another side is the comonomer which is chosen from butene, methyl pentene, hexene or octene, and as for each catalytic converter system (a) general expression (IndH₄) ₂ R " MQ₂ (in formula, each as for Ind equality or it differs, it is the indenyl or the displacement indenyl, R " C₁ - C₄ alkylene bases, is the bridge which includes jiarukirugerumaniumu or silicon or polysiloxane or the alkylphosphine or the amine basis, this bridge is displacement or or it is the unsubstituted,M is metal of the 4th group or vanadium, and each Q is the hydrocarbyl or the halogen which possesses 1 - 20 carbon atoms) the metallocene catalytic converter component which includes bisutetorahidoroindeniru chemical compound; And (b) the catalytic converter component is activated also including the catalytic converter, it becomes.
