    Abstract: A method of making an easily cross-linkable polymer comprises copolymerizing (1) 0,5-50% by weight of an ester of a polymerizable a ,b -ethylenically unsaturated mono- or di-carboxylic acid with a dihydric or higher polyhydric alcohol which bears a chlorine atom at the a -position to a free hydroxyl group and (2) 99,5-50% by weight of one or more unsaturated polymerizable compounds. The esters (1) may be esters of acrylic, methacrylic, maleic or fumaric acid with 3-chlorpropane-diol-(1,2), 2,3-dichlorbutane-diol-(1,4), 3-chlorbutane-triol-(1,2,4), 1,4-dichlorbutane-diol-(2,3), 3-chlor-2-methylpropane-diol-(1,2), or 3-chlor-2-chlormethylpropane-diol-(1,2). Compounds (2) can be acrylic, methacrylic or maleic acid, methyl, ethyl, or butyl acrylate or methacrylate, acrylamide, methacrylamide, acrylonitrile, vinyl acetate, vinyl propionate, acrolein, methyl allyl ketone, isopropenyl ketone, allyl or methallyl alcohol, allyl methyl and ethyl ethers, allyl acetate or propionate, ethylene, propylene, butadiene, vinyl methyl or ethyl ether, vinyl chloride, vinylidene chloride or cyanide, N-vinyl pyrrolidone, N-vinyl carbazole, styrene or mono- or di-methyl styrene. The copolymers may be prepared by bulk, solution, emulsion, suspension or precipitation polymerization, using conventional catalysts, such as peroxides, azo compounds, or redox systems, for example potassium persulphate and azo bis isobutyronitrile. The polymers can be cross-linked at room temperatures by agents which split off hydrogen halide, such as metal oxides, hydroxides and alcoholates. These polymers can be mixed with other polymers.
