Abstract: A process for preparing impact-modified styrene polymers (HIPS) omprises anionic polymerization of styrene in the presence of a rubber in one or more polymerization reactors in succession. The rubber is prepared in solution in an immediately upstream process. The heat of polymerization is utilized to remove the solvent for the rubber, this solvent having a boiling point lower than those of styrene and ethylbenzene, from at least one of the polymerization reactors via distillation with distillative cooling, and the solvent is reintroduced into the process of rubber preparation.

Abstract: A process for the polymerization of dienes in a solvent containing vinyl-aromatic monomers, which is carried out in presence of an organometallic compound of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum or tungsten as catalyst and a Lewis acid as cocatalyst. Independent claims are also included for: (a) a process for the production of high-impact polystyrene, acrylonitrile-butadiene-styrene copolymers or methyl methacrylate-butadiene-styrene copolymers using a rubber solution produced by the above process; (b) a process for the continuous production of impact-modified thermoplastic molding materials containing a rubber-based soft phase dispersed in a hard vinyl-aromatic matrix, by: (1) polymerizing dienes in vinyl-aromatic monomer solution as above in a first reaction zone, (2) transferring the diene rubber to a second zone and subjecting it to anionic or radical polymerization, optionally in presence of further vinyl-aromatic monomer or other comonomers in amounts sufficient to achieve phase inversion and (3) completing the polymerization in a third zone with the amount of vinyl-aromatic monomer required for the impact-modified material; and (c) a process for the production of solutions of rubber in styrene solutions with sterically demanding chelate catalysts.
