ABSTRACT:
The present invention provides a master batch composition based on elastomeric carriers, comprising an organic peroxide, a plasticizer and a filling material and optionally further additives compatible with the organic peroxide, wherein, in addition to the elastomeric carrier, it contains a polyoctenamer.
The present invention also provides a process for the production of a master batch composition, wherein (a) the elastomeric carrier, the polyoctenamer, the plasticizer and optionally a part of the filling material or filling material mixture are homogeneously mixed and thereafter (b) the filling material or the filling material mixture or possibly the remaining amounts thereof, together with the organic peroxide, are incorporated at a temperature below the decomposition temperature of the peroxide.
On the basis of its properties and of the simple and reliable production thereof, the master batch composition according to the present invention is very suitable as a modification agent and especially as a cross-linking initiator for the further working up of elastomeric mixtures.
