Abstract
Copolymers of vinyl toluene and butyl methacrylate, the limiting number average molecular weight of which is between the values Mmax and Mmin determined by the equations Mmax= 3000+8x2 and Mmax=3Mmin where x is the percentage of butyl methacrylate, may be prepared by emulsion polymerisation of the monomers in the presence of alkyl mercaptan, the number of moles of alkyl mercaptan used lying between the limits Ymax and Ymin given by the equations Ymax=3Ymin and Ymin=11/(273-12x+x2) where x is the percentage of butyl methacrylate. The vinyl toluene may be m- or p-vinyl toluene or mixtures thereof. The methacrylate may be n-, sec- or t-butyl methacrylate. The mercaptan may be t-dodecyl or t-amyl mercaptan. Polymerisation may be effected in the presence of initiators, e.g. potassium persulphate, and dispersing agents, e.g. potassium stearate and Turkey red oil, to give latices which may be flocculated by the addition of hydrochloric acid. Examples describe the preparation of latices by the copolymerisation in aqueous emulsion of a commercial mixture of m- and p-vinyl toluenes with (1) n-buytl methacrylate in the presence of potassium stearate (formed in situ), potassium persulphate and t-dodecyl mercaptan; (2) n-butyl methacrylate in the presence of potassium persulphate, potassium stearate and t-dodecyl or t-amyl mercaptan; (3) isobutyl methacrylate in the presence of potassium stearate, potassium persulphate and t-dodecyl mercaptan; and (4) n-buytl methacrylate, ammonium stearate (formed in situ), hydrogen peroxide and t-dodecyl mercaptan. The polymers are soluble in white spirit and may be used in the preparation of dispersible pigment compositions, e.g. for alkyd resin paint media. Specification 936,911 is referred to.
