Abstract

Method for obtaining vinylic copolymer dispersions in a polyhydroxyl compound, having an average molecular weight in number, between 2.10<3> and 8.5.10<3>, by reaction of a mixture of monomers containing acrylonitrile, styrene and other monomer, preferably methyl methacrylate, in the presence of an initiator of the formation of free radical. The polymerization is effected at pressure in a polyhydroxyl compound and with a monomeric composition containing from 90-20% of acrylonitrile, 80-5% of styrene and 70-3% of a vinylic monomer different from the above and preferably constituted by methyl methacrylate, the polymerisation being effected by heat treatment regulated according to the nature of the said initiator and the viscosity it is desired to obtain in the resultant product.
