摘要： The invention relates to a method for continuous production of a solution of rubbers in vinyl-aromatic monomers, which is characterized in that a 10 to 40 % by weight solution or suspension of a rubber is distilled in a hydrocarbon or a hydrocarbon mixture as solvent or suspending agent with a boiling point that is at least 10° C lower than that of the vinyl-aromatic monomers at normal pressure. Before or during distillation, vinyl-aromatic monomers are added to the distillation mixture and distillation is continuously carried out in such a way that a solution of the rubber used ranging from 3 to 10 % by weight is present in the vinyl-aromatic monomers as bottom product, wherein distillation is designed in such a way that the residence time of the rubber in the distillation column ranges from 10 to 30 minutes, the reflux ratio is set between 1 and 5, the temperature of the bottoms ranges from 20 to 80° C, the concentration of the hydrocarbon or the hydrocarbon mixture used in the vinyl-aromatic rubber solution in the distillation bottom product is ≤1 % by weight and the concentration of the vinyl-aromatic monomers in the distillate is ≤5 % by weight.

摘要： The invention relates to a method for polymerizing conjugated diolefins in the presence of catalysts of rare earths and in the presence of aromatic vinyl compounds, and to the use of these diolefins for producing rubber-modified molding materials, especially of the ABS type and impact-resistant polystyrene (HIPS).

摘要： The invention relates to a method and device for removing volatile components, especially solvents, monomers or oligomers, from polymer materials or polymer solutions by evaporating the volatile components from the pre-heated polymer materials in the form of free falling films, strands (4) or foaming liquids in an evaporator system (1). According to the inventive method, once partial or full degassing of the volatile components has occurred in the degassing chamber (9) of the evaporator system (1), the degassed polymer material (4) is directly received by a discharge conveyor device (5) on the lower end of the vaporization system (1), whereby the polymer is prevented from coming into contact with the inner wall of the evaporator system (1).

摘要： A continuous process for the manufacture of impact resistant polymers is disclosed. The process comprises polymerization of a reaction mixture containing vinylaromatic monomers in the presence of soluble rubber and entails shearing at least some of said mixture at a rate of more than 30 000 1/s using a device having no rotating parts. The resulting product is characterized in its low gloss and improved impact properties.

摘要： Conjugated diolefins, optionally combined with other unsaturated compounds that may be copolymerized with diolefins, are polymerized by conducting polymerization of the diolefins in the presence of catalysts based on cobalt compounds, organoaluminum compounds and modifiers in the presence of aromatic vinyl compounds at temperatures ranging from -30 °C to +80 °C. The invention provides a simple method for producing polydiolefin solutions such as polybutadiene with contents of 1,2-units of 10 to 30 % in aromatic vinyl compounds which can be further processed to obtain ABS or HIPS.

摘要： Conjugated diolefins, optionally combined with other unsaturated compounds that may be copolymerized with diolefins are polymerized by conducting polymerization of the diolefins in the presence of catalysts based on compounds of rare earth, cyclopentadiene and organoaluminum compounds in the presence of aromatic vinyl compounds as solvents at temperatures ranging from -30 °C to +100 °C. The invention provides a simple method for producing copolymer solutions such as styrol-butadiene-copolymers having different styrol content and different contents of 1,2- and cis-units in aromatic vinyl compounds in relation to the diolefin, which can be further processed to obtain ABS or HIPS.
