摘要：
The present invention relates to a copolymer comprising units derived from monomers (i) an α-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified with a primary alcohol branched at the β- or higher position, wherein the copolymer has a reduced specific viscosity of up to 0.08. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the copolymer with pendant groups. In addition, the copolymer of the present invention may be useful as a base oil replacement.
