PROCESS FOR PRODUCING POLY ALPHA-OLEFIN FROM 1-OCTENE BY USING PREPOLYMER OF 1-DECENE

摘要

PURPOSE: Provided is a process for producing poly alpha-olefin from 1-octene by using prepolymer of 1-decene, which is a high yield by prepolymerizing 1-decene and reacting 1-octene with it under a high temperature and a high pressure. CONSTITUTION: The poly alpha-olefin being 90cSt or more of coefficient of kinematic viscosity and 135 or more of index of viscosity at 40deg.C is obtained by reacting ethyl aluminum dichloride with t-butyl chloride to prepolymerize 1-decene, and reacting 1-octene with the prepolymerized 1-decene as a catalyst under a high temperature and a high pressure.
