| abstract | 1452439 Plasticizers as polymerization media CESKOSLOVENSKA AKADEMIE VED 10 July 1974 [16 July 1973] 30599/74 Heading C3P Concentrated dispersions and pastes of hydrophilic polymers are produced by a process which comprises polymerizing in a medium comprising one or more plasticizers or a mixture of a plasticizer with one or more saturated or unsaturated fatty acids with 12 or more carbon atoms (unsubstituted or halogenated) and/or one or more alcohols having 8 or more carbon atoms, a mixture of monomers, at least one of which contains one or two carboxylic acid groups, optionally in the form of an anhydride, and the other of which contains more than one vinyl group, and wherein the resulting polymer which has a maximum particle size of 100 microns, is converted into the Na, K, or NH 4 salt form. Suitable plasticizers are esters such as phthalates, adipates, azelates, sebacates, citrates and phosphates. Fatty acids which may be used with the plasticizer(s) are laurie, palmitic, stearic, oleic, elaidic, linoleic and linolenic acids, and suitable alcohols specified are octanol, isooctanol, dodecyl alcohol and cetyl alcohol. Acidic monomers which may be used are acrylic, methacrylic, fumaric, maleic, crotonic, ethacrylic, citraconic, mesaconic, itaconic and ethyl maleic acids. The monomer containing more than one vinyl group may be, for example, divinyl benzene, ethylene glycol di(meth)acrylate, diethylene glycol di(meth)acrylate, glycol divinyl ether, divinyl adipate, allyl vinyl ether, dialkyl fumarate, triallyl cyanurate, divinyl toluene, trivinylbenzene and divinyl naphthalene. In the examples, copolymers of acrylic acid and/or methacrylic acid and divinyl benzene, and maleic acid/divinyl benzene, are produced using plasticizers, fatty acids and alcohols selected from those specified. |
