Abstract
A process is described for the preparation of mixtures for processing as plastisols or organosols, wherein at least one known plasticizer, at least one first vinyl chloride copolymer and at least one vinyl chloride homopolymer or a second vinyl chloride copolymer are mixed together, if appropriate with the addition of further known substances. The first copolymer is a specific vinyl chloride graft copolymer, of which 5 to 70% by weight are employed, relative to the total quantity of polymers present in the mixture. It contains 99.5 to 88% by weight of polymerized units of vinyl chloride, 0.1 to 11.9% by weight of polymerized units of vinyl acetate and 0.1 to 2.2% by weight of polymerized units of ethylene. The remaining polymer(s) employed is/are prepared in accordance with customary processes. Mixtures prepared in this manner produce plastisols or organosols which have a low viscosity and good stability on storage and which also enable uniform coatings to be obtained by applying a thin layer.
