    • 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.
    • 通过阴离子聚合从二烯单体和苯乙烯单体制备耐冲击聚苯乙烯的方法,其中1)在阶段1)橡胶溶液由二烯单体或二烯单体和苯乙烯单体制备,使用 碱金属有机化合物作为引发剂,同时使用溶剂,然后2)在阶段2)中,将苯乙烯单体加入到橡胶溶液中,并将所得混合物阴离子聚合,得到耐冲击聚苯乙烯,其中 ,在阶段1之后)和阶段2之前),向橡胶溶液中加入有机铝化合物和碱金属氢化物。
