Abstract: Flatting agents for coatings obtained by reacting a polyolefin wax (A) with a vinyl aromatic compound (B) and a copolymerizable Alpha , Beta -olefinically unsaturated dicarboxylic anhydride (C), optionally partially replaced by at least one Alpha , Beta -olefinically unsaturated monocaraboxylic acid, the molar ratio of (B) to (C) being from 0.7:1 to 1:0.7 and the sum of the weights of (B) and (C) being from 2 to 50 percent by weight of the weight of polyolefin wax (A). The reaction is carried out at temperatures of from 100* to 200*C, in the presence or absence of conventional free-radical polymerization initiators. The agents are particularly suitable for coatings containing organic solvents.

Abstract: Continuous production of styrene polymers which contain an expanding agent and which are in the form of granules by extrusion of a mixture of a melt of the polymer with the expanding agent and rapid cooling of the extruded mixture, wherein excess expanding agent is first mixed with the melt and then the excess of expanding agent is evaporated. In this way both the production of a homogeneous mixture and the cooling of the mixture prior to extrusion to temperatures just above the softening point of the mixture are facilitated.

Abstract: PROCESS FOR THE PRODUCTION OF IMPACT-RESISTANT POLYMERS BY THE CONTINUOUS POLYMERIZATION OF A SOLUTION OF A DIENE ELASTOMER OR ELASTOMERIC COPOLYMER OF ETHYLENE AND PROPYLENE, THE STARTING MATERIALS BEING FIRST PARTIALLY POLYMERIZED TO SUCH AN EXTENT THAT THE SOLIDS CONTENT OF THE MIXTURE IS 1.1 TO 2 TIMES THE CONTENT OF DIENE ELASTOMER BUT NOT MORE THAN 16% BY WEIGHT, THEN INTRODUCED INTO AN ISOTHERMAL POLYMERIZATION STAGE WHERE A MIXTURE CONTAINING LESS THAN 50% BY WEIGHT OF SOLIDS IS PREPARED AT A TEMPERATURE OF FROM 50* TO 150*C. WHILE MIXING, WHICH MIXTURE IS TOTALLY POLYMERIZED IN THE DOWNSTREAM CONTINUOUS POLYMERIZATION STAGES AT A TEMPERATURE OF UP TO 250*C. TO GIVE A MIXTURE CONTAINING MORE THAN 60% BY WEIGHT OF SOLIDS, AND THEN FREED IN A CONVENTIONAL MANNER FROM VOLATILE CONSTITUENTS.
