摘要
Treatment of aqueous suspensions of vinyl chloride polymers containing vinyl chloride monomer so as to inhibit wet-foaming therein, by adding a glyceride of an optionally substituted saturated or unsaturated carboxylic acid containing 6 to 20 carbon atoms (e. g. glycerol monoricinoleate). Solid-foaming can also be inhibited by adding a wetting agent (such as partially hydrolysed polyvinyl acetate PVA) and a preferred formulation for effecting the treatment comprises an aqueous emulsion of the glyceride having PVA as the emulsion stabiliser. t
