OIL RESISTANT THERMOPLASTIC RUBBER Russian patent published in 2009 - IPC C08L9/02 C08L23/10 C08L23/16 C08L23/26 C08L61/10 C08L75/00 C08K5/01 C08K5/10

Abstract RU 2366671 C1

FIELD: chemistry.

SUBSTANCE: rubber composition consists of, wt %: polypropylene - 3-21, butadiene-nitrile rubber - 22-55, olefin rubber - 2.5 -9.5, modificator, cross-linking agent for rubbers - 1.5-3.5, activator - 0.18-0.3, plasticiser - 3.0-7.5, mineral oil - 8-40. The composition contains polyisocyanate containing not less than two isocyanate groups (0.05-2.3 wt %) as a modificator and polypropylene with 1-6% of grafted maleic anhydride or maleic acid - 6-20 wt %. Plasticiser solubility parametre of is not less than 18 (kJ/m³)^1/2.

EFFECT: oil resistance enhancing, decrease of relative residual elongation and melt flow index.
