Abstract

1457393 Production of ethylene polymer/unsaturated polyester compositions BAYER AG 14 Feb 1975 [15 Feb 1974 23 Feb 1974 19 Oct 1974] 6277/75 Heading C3P In a process for producing a dispersion of an ethylene polymer in a solution of an unsaturated polyester in a vinyl aromatic monomer, a solution of the ethylene polymer in the vinyl aromatic compound, and a solution of the unsaturated polyester in the vinyl aromatic compound, are combined at 50-120‹ C. in the presence of a dispersing agent and in a zone of high turbulence, and the resulting mixture is withdrawn from this zone and stirred at 50- 120‹ C. until a low viscosity pourable mixture is obtained. The zone of high turbulence may be produced in a stirred kettle which has a disc stirrer and flow breakers. The stirrer shaft may be hollow and one of the said solutions may be introduced directly into the kettle, and the other through the hollow shaft. In the examples ethylene polymers used are polyethylene and various ethylene/vinyl acetate polymers. The monomer used is styrene.
