Abstract
Impact-resistant polystyrenes are produced by the polymerization of a styrene which contains a stabilized natural or synthetic rubber in solution or in finely divided swelled homogeneous state, and from 0,1 to 5%, based on the total weight of the mixture, of one or more esters of one or more acrylic acids, e.g. methyl, ethyl, propyl and butyl acrylates and methacrylates. In addition to styrene itself there may be used substituted styrenes, e.g. alphamethyl styrene and vinyl toluene. As a stabilized synthetic rubber there is specified a butadiene-styrene copolymer containing 1,2% of styrenized phenol. The polymerization of the mix may be carried out in bulk, or in suspension or emulsion in water containing suspending and emulsifying agents. Polymerization catalysts may be employed, e.g. di-tert. butyl and benzoyl peroxides, tert. butyl perbenzoate, azodiisobutyronitrile and potassium persulphate.
