Improvements in or relating to the manufacture of polyvinyl chloride pastes

Abstract

Abstract A paste suitable for coating fabrics comprises polyvinyl chloride, polystyrene of a degree of polymerization greater than 1000 in an amount not exceeding 5 per cent by weight of the polyvinyl chloride and a solvent plasticiser for the polystyrene, with or without an additional polystyrene solvent. Specified additional solvents are solvent naphtha, toluene and xylene. Suitable plasticisers are tricresyl phosphate, dibutyl, dihexyl and dioctyl phthalates, which may incorporate extenders such as chlorinated paraffin wax. Stabilisers, e.g. lead silicate or stearate, fillers, e.g. china clay, pigments, e.g. ultramarine blue, carbon black, titanium dioxide or lead chromate, and dispersing agents such as those sold under the Registered Trade Mark "Lubrol W" may be added.
