Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a copolymer suitable for the use in or as a lubricant and compatible with other low polar lubricating fluids. SOLUTION: The copolymer comprises a 12-18C α-olefin and a di-ester of an α,β-ethylenically unsaturated dicarboxylic acid, wherein a 3-7C linear or branched alkyl alcohol is used as an esterifying agent of the dicarboxylic acid. The copolymer has a weight average molecular weight of >3,500. COPYRIGHT: (C)2009,JPO&INPIT
