EPOXIDIERTE POLYALPHA-OLEFIN-OLIGOMERE MIT SCHMIEREIGENSCHAFTEN
摘要
Epoxy functionalized polyalpha-olefin lubricants compositions are prepared with superior properties by epoxidizing the olefinic bond of oligomers prepare by oligomerizing C6-C20 alpha-olefins with reduced valence state chromium catalyst on silica support. The invention encompasses a product of reaction made by epoxidizing C30+ polyalpha-olefin oligomeric hydrocarbon lubricant having a branch ratio of less than 0.19 and pour point below -15 DEG C. in the presence of an epoxidizing amount of an epoxidizing agent wherein said product comprises a mixture of 2-dialkyl oxirane and 1,2-dialkyl oxirane having between an average of C30 and C1000 carbon atoms, said mixture having a branch ratio of less than 0.19 and pour point below -15 DEG C. The invention further encompasses blends and additive compositions of the novel epoxidizing polyalpha-olefins.
