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: Process for the prepn. of olefinically unsatd. cpds. by catalytic oxidn./oxidative dehydrogenation by oxygen transfer from a previously oxidised oxygen transfer agent (I) serving as catalyst in the absence of molecular O2, with regeneration of the catalyst when it becomes exhausted, where during the working phase of the catalyst (oxidn./dehydrogenation step) the residence time, the space velocity and/or the temp. of the reactants are adjusted either continuously or stepwise to match the momentary state of activity of the redox catalyst such that the residence time of the reactants in the freshly regenerated catalyst (i.e. at the beginning of the reaction) is made shorter or the space rate is made higher and/or the temp. is made lower than the corresp. parameters in the partially reduced catalyst.
