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.
摘要(中):
本发明涉及包含衍生自单体的单体(i)α-烯烃和(ii)烯键式不饱和羧酸或其在伯或更高位上被支化的伯醇酯化的衍生物的共聚物,其中共聚物具有 比粘度降低至0.08。 本发明还提供含有所述共聚物的润滑组合物。 本发明还提供了通过向带有侧基的共聚物供给润滑粘度的油来控制粘度指数的方法和用途。 此外,本发明的共聚物可用作基础油替代物。
