ABSTRACT:
In the preparation of impact-resistant alkenyl aromatic resinous polymers such as impact polystyrene containing halogenated monomer such as a brominated methacrylate, improved physical properties are obtained if the brominated monomer is added after phase inversion of the rubber and at a rate sufficiently slow as to maintain the identity of the rubber particles.
