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.

Plastified novolaks as additive to rubber mixtures

Mixtures containing at least one functionalized low-molecular rubber A, at least one cross-linking agent B having groups which are reactive with respect to the functional groups of the rubber A, accelerators/catalysts C for the cross-linking reaction between A and B, possibly reactive diluents D, vulcanization chemicals E, and also fillers F and auxiliary substances G, with at least one of the average functionalities of the constituents A and B being at least 2, and their use as anti-corrosive coating agents.

Coating with functionalized rubber, crosslinker, accelerator/catalyst and vulcanizer

Urethane-modified novolaks which are prepared by simultaneous reaction of a monohydric or polyhydric phenol (A) with an oxo compound (aldehyde or ketone) (B) and a urethane (C) in the presence of an acidic catalyst (D) at an elevated temperature of 60.degree. to 200.degree. C. and contain no interfering amounts of free starting phenol, and their use as adhesion improvers in rubbers, in particular rubbers containing reinforcing media such as steel cord or textile fibers.
