Process for the production of polymer-bound rubber chemicals, characterized in that the rubber chemicals and optionally additives are finely dispersed in a low molecular weight polymerizable liquid, polymerization is then initiated, optionally after adding a further component which reacts with the polymerizable liquid to form a polymer, and the solid, homogeneous mixture of rubber chemicals and polymer so formed is optionally converted into a form suitable for use.

Process for the production of polymer-bound rubber chemicals

Rubber chemical preparation consisting of or comprising rubber chemicals in finely divided form and a carrier liquid, in which the rubber chemical particles have a mean diameter (weight average d.sub.50) from 2 .mu.m to 20 .mu.m, preferably &lt;10 .mu.m, and exhibit a very narrow diameter distribution corresponding to .delta.d.sub.10 -d.sub.90 .ltoreq.20 .mu.m, preferably &lt;10 .mu.m.

Rubber chemical preparation

Rubber components of a vulcanizable rubber composition are homogenized by adding to the composition, prior to vulcanization, a phenolic resin formed by reacting a bisphenol A residual resin with chlorinated C.sub.4 to C.sub.8 hydrocarbons in the presence of a Friedel-Crafts alkylation catalyst.
