Abstract

"PROCESSO CONTìNUO NA FASE DE VAPOR PARA A POLIMERIZAçãO DE OLEFINAS". Um processo contínuo na fase de vapor para polimerização de olefinas compreende a polimerização ou copolimerização de olefinas na presença de (i) um catalisador de polimerização de olefinas formado a partir de (A) um componente de catalisador sólido de titânio contendo magnésio, titânio e halogênio como ingredientes essenciais, (b) um componente de catalisador de composto orgânico de alumínio e (c) SiR^ 1^R^ 2^(OR^ 3^) 2, na qual cada um de R^ 1^ e R^ 2^ um grupamento ciclopentila, um grupamento ciclopentenila, um grupamento ciclopentadienila, um grupamento ciclopentila substituido por 1 a 4 grupamentos alquila de 1 a 4 átomos de carbono, um grupamento ciclo-pentenila substituído por 1 a 4 grupamentos alquila de 1 a 4 átomos de carbono, um grupamento ciclopentadienila substituído por 1 a 4 grupamentos alquila de 1 a 4 átomos de carbono, ou um grupamento indenila, um grupamento indanila, um grupamento tetraidroindenila ou um grupamento fluorenila que pode ser substituído por 1 a 4 grupamentos alquila de 1 a 4 átomos de carbono; e R^ 3^ é um grupamento metila ou um grupamento etila, e (ii) 0,1 a 20 partes em peso de um agente-tensoativo com base em 100 partes em peso do catalisador de polimerização de olefinas. De acordo com o processo contínuo de polimerização de olefinas na fase de vapor, nenhuma obstrução ocorre durante a polimerização e pode ser produzida uma poliolefina com um alto índice de estéreo-regularidade com um alto grau de atividade de polimerização."CONTINUOUS STEAM PROCESS FOR THE POLYMERIZATION OF OLEFINS". A continuous vapor phase process for olefin polymerization comprises the polymerization or copolymerization of olefins in the presence of (i) an olefin polymerization catalyst formed from (A) a solid titanium catalyst component containing magnesium, titanium and halogen as essential ingredients, (b) an organic aluminum compound catalyst component and (c) SiR ^ 1 ^ R ^ 2 ^ (OR ^ 3 ^) 2, in which each of R ^ 1 ^ and R ^ 2 ^ a cyclopentyl group, a cyclopentenyl group, a cyclopentadienyl group, a cyclopentyl group substituted by 1 to 4 alkyl groups of 1 to 4 carbon atoms, a cyclopentenyl group substituted by 1 to 4 alkyl groups of 1 to 4 carbon atoms, a cyclopentadienyl group substituted by 1 to 4 alkyl groups of 1 to 4 carbon atoms, or an indenyl group, an indanyl group, a tetrahydroindenyl group or a fluorenyl group that can be substituted included by 1 to 4 alkyl groups of 1 to 4 carbon atoms; and R3 is a methyl group or an ethyl group, and (ii) 0.1 to 20 parts by weight of a surfactant based on 100 parts by weight of the olefin polymerization catalyst. According to the continuous process of olefin polymerization in the vapor phase, no obstruction occurs during polymerization and a polyolefin with a high stereo-regularity index with a high degree of polymerization activity can be produced.
