Abstract

1491136 Preparation of aqueous polymer powder dispersions CHEMISCHE WERKE HULS AG 14 Feb 1975 [16 Feb 1974] 6317/75 Headings C3P and C3R An aqueous dispersion of a plastics powder is formed by mixing at below 50‹ C. (i) a plastics powder of particle diameter not more than 100 microns, (ii) 0À1 to 5 wt. per cent (based on the plastics powder) of a water soluble thickener; (iii) 0À5 to 6 wt. per cent (based on the plastics powder) of a sodium, potassium, or ammonium salt of a phosphoric acid and (iv) water. Preferably, the plastics powder is mixed with an aqueous solution of components (ii) and (iii). Suitable water soluble thickeners are methyl and hydroxy ethyl cellulose, polyacrylic acid ammonium salt, and vinyl pyrrolidone copolymers. In the examples, dispersions of powders of PVC, polystyrene and a C 12 polyamide, are prepared.
