    摘要： In a process for preparing block copolymers of styrene or its equivalents on the one hand and of butadiene or its equivalents on the other hand by sequential anionic polymerization, in which a first monomer and the organometallic compound serving as initiator are first of all combined to form a reaction mixture and the reaction is continued until at least part of the first monomer has been consumed, and then at least one further monomer is added and is in each case partially or completely reacted, the polymerization is carried out continuously in a conventional manner in a tubular reactor, the reaction of in each case one monomer being carried out in each case in one reactor section and at least two reactor sections being separated by a mixing stretch.

    摘要： A process is described for preparing styrene polymers by continuous anionic polymerization, the monomer or monomers and the organometallic compound serving as starter (initiator) being added in solution to a tubular reactor operating essentially without backmixing and being left in the reactor until the monomer has been consumed, wherein the polymerization is carried out in at least two successive tubular reactor sections operating in each case essentially adiabatically, with in each case at least one heat exchanger arranged between the sections. If desired a proportion of the starter and/or of the monomer is added to at least one reactor connected downstream of the first reactor.

    摘要： Thermoplastic molding compositions based on rubber-modified styrene-acrylonitrile copolymers containing a halogenated styrene oligomer as the effective flame-proofing agent which is sufficiently heat-stable, does not interfere with processing on conventional machinery, does not corrode or cause coatings on such machinery, and has virtually no adverse effect on the impact strength of the polymers. The flameproofing agent as a rule has a degree of polymerization of from 3 to 200 and can be incorporated into the polymer by conventional methods; the polymer may or may not contain additional synergistic agents and processing auxiliaries, which are incorporated in the conventional manner and in the conventional amounts.

    摘要： 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.
