More Information
Summary:The present invention is directed to novel polyalkyl(meth)acrylates comprising specified amounts of long-chain alkyl(meth)acrylates and functional monomers, their preparation, lubricant compositions comprising such polyalkyl(meth)acrylates and their use as viscosity index (VI) improvers with good fuel economy as well as soot-dispersant function and equal or even improved deposits in lubricant compositions, especially in engine oil (EO) compositions. 本发明涉及新的包含特定量的(甲基)丙烯酸长链烷基酯和官能单体的聚(甲基)丙烯酸烷基酯、它们的制备、包含这样的聚(甲基)丙烯酸烷基酯的润滑剂组合物，以及它们作为粘度指数(VI)改进剂的用途，所述粘度指数(VI)改进剂具有良好的燃料经济性以及烟炱分散功能，并且在润滑剂组合物中，尤其是在发动机油(EO)组合物中具有相同或甚至改进的沉积物性能。
