Abstract:
This disclosure is directed to an additive package for a lubricant composition that provides improved compatibility with fluoropolymer seals. The additive package comprises a seal compatibility additive. The disclosure is also directed to a lubricant composition comprising a base oil and a seal compatibility additive. The seal compatibility additive improves the compatibility with fluoropolymer seals of the resultant lubricant composition.

Abstract:
A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free-radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C8-C10 alkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C8-C10 alkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C8-C10 alkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Abstract:
Una composición lubricante que tiene propiedades viscométricas no newtonianas mejoradas incluye por lo menos 85 por ciento en peso de un aceite de base y 1 a 15 por ciento en peso de un aditivo lubricante. El aditivo mismo incluye 10 a 80 por ciento en peso de un aceite diluyente y 30 a 80 por ciento en peso de un mejorador de índice de viscosidad co-polimérico aleatorio. El mejorador de índice de viscosidad es el producto de polimerización por radicales libres de por lo menos 5 a 15 por ciento en peso de metacrilato de metilo y 5 a 95 por ciento en peso de un (met)acrilato de alquilo de C8-C10. El aditivo se forma usando un método que incluye el paso de hacer fluir el aceite diluyente, el metacrilato de metilo, el (met)acrilato de alquilo de C8-C10, y un iniciador de radicales libres. El método también incluye los pasos de hacer fluir el aceite diluyente en un reactor, hacer fluir el metacrilato de metilo y el (met)acrilato de alquilo de C8-C10 en el reactor independientemente del iniciador de radicales libres, y hacer fluir el iniciador de radicales libres en el reactor.
