1- 1- A method for preparation of polyalphaolefins by reacting 1-octene with preliminary-polymerized 1-decene

摘要

The invention mainly as high under the industrial engine polyalphaolefins which may be used for peak Contractors passage normal conditions relates to a method for producing in a high yield, 1-decene with ethyl aluminum dichloride (EADC) and t- butyl chloride (TBC) for not less than a kinematic viscosity of 90cSt at 40 ℃ by reacting 1-octene, and under normal conditions by a prepolymerization product with a catalyst, the viscosity index may be 135 or more to produce a high viscosity polyalphaolefin contract.
