Novolacs (I) plasticized with terpene-like unsaturated natural substances (C), in which the weight ratio of phenol or phenol derivative (B) to component (C) is (1 : 6)-(6 : 1) are used as modifier resins for rubber mixtures to increase tear strength and reduce compression set in the vulcanized material. Independent claims are also included for (1) a method for increasing the tear strength and reducing the compression set of vulcanized rubber by adding modifier (I) to a rubber mixture and vulcanizing the mixture in a mould (2) molded vulcanized rubber parts and tires produced by this method, especially tires for cars, lorries, earth-moving machines, tractors and/or aircraft, V-belts, transmission belts, toothed belts, tubing, rubber rollers, conveyor belts, rubber-coatings on solid bodies, supporting matrices for abrasive wheels and/or friction linings, and seals.
