  • Plastified novolaks as additive to rubber mixtures
    Patent number: 6828391
    Abstract: Use, as modifier resin for rubber mixtures, of novolaks ABC plastified with terpene-type olefinically unsaturated natural substances C, where the ratio of the molar amount of the phenol or phenol derivative B and the molar amount of the natural substance C in the modified novolak is from 1:6 to 6:1, process for increasing the tear propagation resistance and reducing the compression set of rubber vulcanizates by adding these modifier resins to rubber mixtures, and components molded from vulcanizates thus prepared.
