ABSTRACT:
Novel lubricant compositions comprising polyalphaolefins are disclosed having high viscosity indices with low pour point. The compositions are characterized by a uniform molecular structure with low branch ratios. The invention describes a liquid lubricant composition comprising C.sub.30 -C.sub.1300 hydrocarbons, said composition having a branch ratio of less than 0.19, weight average molecular weight between 300 and 45,000 number average molecular weight between 300 and 18,000, molecular weight distribution between 1 an 5 and pour point below -15.degree. C. 1-decene trimer comprising 9-methyl, 11-octylheneicosane and 11-octyldocosane is disclosed.
