Abstract
Liquid homopolymers or copolymers are made by subjecting an aqueous medium containing one or more ethylenically unsaturated compounds and a mercaptan to the action of light. Unsaturated compounds specified are methyl and ethyl acrylates, C1-C4 alkyl methacrylates, butadiene and isoprene and mixtures of dienes with methyl acrylate, methacrylic acid or styrene. Mercaptans specified are octyl, decyl, n-dodecyl, tert-dodecyl, tetradecyl and hexadecyl mercaptans, including a mixture of tert.-dodecyl, tert.-tetradecyl and tert.-hexadecyl mercaptans. Polymerization is preferably carried in the presence of a photosensitizer, e.g. anthraquinone, 1-chloroanthraquinone, dichloramine B, N-bromosuccinimide, diazotized sulphanilic acid, azobisisobutyronitrile, diacetyl, benzil, benzoin, uranium dioxide, uranyl nitrate and iron salts, including mixtures of substances which absorb light of different wavelengths, e.g. benzoin and uranyl nitrate. Polymerization may also be carried out in the presence of potassium persulphate as an initiator. The illumination used may consist of light having a wavelength in the region of 2,000-7,000 . The aqueous polymerization medium may contain an emulsifier such as potassium oleate, sulphated methyl oleate or the sodium salts of higher secondary alkyl sulphates.
