| titleOfInvention | Improvements in or relating to interpolymers |
| abstract | Film-forming ternary polymers are obtained by polymerizing a mixture comprising 30 to 80 per cent of an alkyl acrylate, the alkyl group containing 1 to 4 carbon atoms, 10 to 65 per cent of a vinyl ester of an aromatic acid, the carboxyl group being attached to the nucleus, and 5 to 40 per cent of a monovinyl aromatic compound, the vinyl group being attached to the nucleus. In addition to or as a partial replacement for the lower acrylates, higher acrylates in which the alkyl group contains 5 to 10 carbon atoms may be used. Specified vinyl aromatic esters are vinyl benzoate, chlorobenzoate, toluate, chlorotoluate, naphthoate and pyrocatechuate. The monovinyl aromatic compound may be styrene, o- and p-methyl styrenes, vinyl naphthalene, and nuclear-substituted chloro- and methoxy-styrenes and vinyl naphthalenes. A fourth mono-olefinic compound such as vinyl chloride, vinylidene chloride, vinyl acetate, diethyl maleate, acrylonitrile, higher alkyl acrylates, and furfuryl and tetrahydrofurfuryl acrylates may be present, but three components only are preferred. Polymerization may be effected in bulk, solution or emulsion in the presence of the usual emulsifiers or protective colloids. When the interpolymer is to be used as a coating material, the medium is preferably an organic solvent in which both monomer and polymer are soluble, e.g. ethyl acetate, toluene, ethyl acetate-toluene mixtures, methyl ethyl ketone, or mixtures thereof with toluene, acetone, toluene-acetone mixtures, cyclohexanone, chlorotoluene, cyclopentanone, and tetrahydrofurfural, to which may be added benzene, chlorobenzene, naphthalene, nitrotoluene, nitrobenzene and ethylene dichloride. A catalyst is generally employed and may be actinic light, hydrogen peroxide, benzoyl peroxide, o,o1-dichlorobenzoyl peroxide, caproyl peroxide, caprylyl peroxide, pelargonyl peroxide, cumene hydroperoxide, tert.-butyl hydroperoxide, 1-hydroxy-cyclohexyl hydroperoxide, tert.-butyl diperphthalate, tert.-butyl perbenzoate, sodium, potassium and ammonium persulphate, and sodium perborate and percarbonate. Polymerization is preferably carried out in an inert atmosphere at temperatures of from -30 DEG to 100 DEG C. The polymer solutions form strongly adherent lacquer coatings on aluminium, iron, steel, brass, copper, tin, lead and glass surfaces and are not sensitive to water. |
