FUNCTIONALIZED OLEFIN COPOLYMERS WITH MONOAMINE TERMINATED POLYETHER AND LUBRICATING OIL COMPOSITIONS |
摘要 |
A reaction product, useful as a viscosity index improver in a lubricating oil, reacting: a) an oil soluble ethylene-alpha olefin copolymer comprising from 10 to less than 80 weight % ethylene and greater than 20 up to 90 weight % of at least one C3 to C28 alpha olefin, having a number average molecular weight from 5,000 to 120,000 and grafted with 0.5 to 5 weight % of an ethylenically unsaturated acylating agent, with b) a hydrocarbyl substituted poly(oxyalkylene) monoamine of the formula: R1—(O—CHR2—CHR3)x-A wherein: R1 is a hydrocarbyl group having from 1 to 35 carbon atoms; R2 and R3 are each independently hydrogen, methyl, or ethyl and each R2 and R3 are independently selected in each —O—CHR2—CHR3— unit; A is amino, —CH2amino or N-alkyl amino having 1 to 10 carbon atoms; and x is an integer from 2 to 45. |
