42 | Oil soluble ionic graft copolymers | US945466 | 1992-09-16 | US5328960A | 1994-07-12 | Frederick C. Loveless |
A lubricant additive which is the reaction product of polyvinylpyridine and sulfonated polyisobutylene is oil soluble and provides clear solutions in oil. These reaction products are ionic graft copolymers. The reaction products of the invention form solutions with lubricant base stocks, such as mineral oil, and are excellent Viscosity Index enhancers. Moreover, the reaction products of the invention act as thickening agents for the oil or grease of the lubricant composition of the invention, at very low levels of reaction product content. | ||||||
