    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyvinyl alcohol-polyether-graft copolymer, by which the product is obtained in a form capable of being advantageously used by an injection molding method or a film extrusion method, and by which the graft copolymer containing the vinyl alcohol in a copolymerized form and having a surely adjustable hydrolysis degree can simply be produced without accompanying a complicated process, especially a steam distillation process and a spray drying process.
    SOLUTION: This method for producing the graft copolymer (P2) having repeating units originated from the vinyl alcohol and having polyether groups comprises reacting a graft copolymer (P1) having repeating units originated from a vinyl alcohol ester and having polyether groups with water and/or at least one 1 to 6C alkanol in the presence of a catalyst in an extruder. Namely, the method for preparing the graft copolymer having repeating units originated from the vinyl alcohol and having the polyether groups comprises reacting the corresponding graft copolymer based on the vinyl alcohol ester with the water and/or at least one 1 to 6C alkanol in the presence of a catalyst in an extruder.

    Abstract: The present invention relates to thermoplastic molding compositions comprising a mixture of (A) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a methyl methacrylate polymer, (B) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a copolymer obtainable by polymerizing a styrenic monomer and a vinyl cyanide, and (C) from 1 to 40% by weight, based on the sum of components (A), (B) and (C), of a graft copolymer obtainable from (C1) from 60 to 90% by weight, based on (C), of a core obtainable by polymerizing a 1,3-diene and a styrenic monomer, (C2) from 5 to 20% by weight, based on (C), of a first graft shell, and (C3) from 5 to 20% by weight, based on (C), of a second graft shell composed of an alkyl (meth)acrylate polymer, with the proviso that the ratio of (C2) to (C3) is in the range from 2:1 to 1:2.

    Abstract: Preparation of hardly modified, thermoplastic molded mass comprises preparing a thermoplastic solution through mass-, solution-, emulsion- or suspension polymerization; preparing a rubber dispersion through emulsion polymerization; mixing the thermoplastic solution and the rubber dispersion; and evaporating water and organic solution, emulsion-, suspension and dispersion agent and agglomerating the rubber, and melt mixture of thermoplast and rubber. Preparation of hardly modified, thermoplastic molded mass comprises preparing a thermoplastic solution through mass-, solution-, emulsion- or suspension polymerization; preparing a rubber dispersion through emulsion polymerization; mixing the thermoplastic solution and the rubber dispersion; and evaporating water and organic solution, emulsion-, suspension and dispersion agent and agglomerating the rubber, and melt mixture of thermoplast and rubber (where the mixing and the evaporating steps are carried out simultaneously together or separately in two successive procedure steps; and the evaporation step is carried out in an evaporator or deaerator). An independent claim is included for a hardly modified, thermoplastic molded mass produced by the process.
