The present invention provides an additive that modifies the temperature behavior of a non-crosslinkable organic medium, such as engine oil, gear oil, etc., in high temperature applications of at least about 100 ° C. Rubber particles obtained by crosslinking rubbers such as polybutadiene, polyisoprene, styrene-butadiene rubber, acrylate rubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate copolymer, polychloroprene, and epoxidized natural rubber. Cross-linked microgels) are used as additives for non-crosslinkable organic media such as engine oils, gear oils, hydraulic fluids and compressor oils. [Selection figure] None |
