摘要

A liquid polymer having a very high viscosity of between 250 cSt and 15,000 cSt at 210 DEG F, is prepared by polymerizing one, or a mixture of more than one, n-alpha olefine represented by the formula R - CH = CH2, in which R is an alkyl radical containing from 6 to 8 carbon atoms, in the presence of a catalyst system formed at a temperature in the range of 0 DEG -150 DEG C by a catalyst consisting of TiCl4 and a polyiminoalane having the formula: --Al---N-- ¦¦ HR n IN WHICH N IS A WHOLE NUMBER NOT GREATER THAN 50 AND R is an isopropyl radical, and in an atmosphere consisting essentially of an inert gas. The liquid polymer of very high viscosity so formed is useful as a lubricant.
