Abstract

In the aqueous emulsion polymerization of monomeric polymerizable material comprising a major proportion of styrene, alpha methyl styrene or their chlor-, methyl- and/or ethyl-nuclear substituted derivatives, an alkali metal, amine or ammonium salt of a mono-ester of delta4-tetrahydrophthalic acid or an analogue thereof capable of being made by the Diels-Alder reaction, with a saturated aliphatic alcohol of 5-32 carbon atoms, is used as emulsifying agent in an amount of 0.25 to 10 per cent by weight of the aqueous phase. Emulsifying agents specified are the sodium salt of lauryl hydrogen 3 : 6-endomethylene delta4-tetrahydrophthalate and the potassium salt of the stearyl mono-ester of the same acid. Polymerization is preferably effected at a pH greater than 3 and isopropyl benzene hydroperoxide may be used as catalyst. Other monomers which may be present in the polymerizable material include divinyl benzene, vinyl naphthalene, vinyl acetate and crotonate, acrylic and methacrylic acids, acrylonitrile, methyl methacrylate, cyclohexyl acrylate, ethyl vinyl ketone, butadiene and isoprene. The emulsifying agent may be removed from the polymer by hydrolysis and steam distillation. Alternatively, the latex may be evaporated to dryness or coagulated with formic acid to recover the polymer.
