Abstract: Process for preparation of impact-resistant polystyrene from diene monomers and from styrene monomers via anionic polymerization, where 1) in a stage 1) a rubber solution is prepared from the diene monomers, or from the diene monomers and from the styrene monomers, using an alkali metal organyl compound as initiator and with concomitant use of a solvent, and then 2) in a stage 2), styrene monomer is added to the rubber solution, and the resultant mixture is polymerized anionically to give the impact-resistant polystyrene, and where, after stage 1) and prior to stage 2), an organylaluminum compound and an alkali metal hydride are added to the rubber solution.

Abstract: An anionically polymerized impact-modified polystyrene has a yield stress of at least 24 MPa, measured at 23° C. to DIN 53455 and a hole impact strength of at least 11 kJ/m2, measured at 23° C. to DIN 53753, measured in each case on a specimen produced to ISO 3167. A preparation process is described.

Abstract: A method for the production of homo- or co-polymers from styrene monomers and/or diene monomers by anionic polymerisation, involves stopping the polymerisation by adding a mixture (Z) containing chain cleavage agent(s) (K) and emulsifier(s) (E). Independent claims are also included for: (1) a mixture (Z) as defined above for stopping the anionic polymerisation of styrene and/or diene monomers; (2) homo- and/or co-polymers of styrene and diene monomers obtained by this method; and (3) molded products, film, fibres and foam made from these homo- or co-polymers.

Abstract: In transparent block copolymers (I) with star structure having rigid blocks S1 and S2 of vinyl-aromatic monomer differing in molecular weight and random flexible blocks (B/S)1 and (B/S)2 of vinyl-aromatic and diene monomers differing in monomer ratio, at least one arm of the star has the block sequence S1-S2-(B/S)1-(B/S)2, at least one has the block sequence S2-(B/S)1-(B/S)2 and the diene monomer fraction of (I) is 15-20 wt.%. An independent claim is also included for transparent polymer blends containing 50-99.9 wt.% block copolymer(s) (I) and 0.1-50 wt.% other vinyl-aromatic polymer(s) (II).

Abstract: An anionically polymerized tough impact polystyrene of melt/volume flow rate MVR of at least 8-20 cm3/10 minutes (as measured by EN ISO 1133 at 200 degrees C test temperature and 5 kg nominal load) is new. Independent claims are also included for: (1) a process for preparation of the tough impact polystyrene by anionic polymerization of styrene in the presence of a styrene/butadiene block copolymer, using an alkali metal organyl as anionic polymerization initiator, e.g. s-butyl lithium, and an aluminum, magnesium or zinc organyl as retarder, e.g. triisobutylaluminum (TIBA); (2) a shaped body, film, fibers or foam obtained from the tough impact polystyrene.
