Abstract

A heat-reactive polymer solution system is made by copolymerizing in the presence of an initiator and a solvent at least one ethylenic monomer and a monomer containing a reactive group selected from carboxyl, hydroxyl, methylol, primary or secondary amine, epoxy, aldehyde and isocyanate, and then blending the copolymer with a similarly prepared second copolymer containing a reactive group of the above type which is reactive with the first copolymer, both copolymers being obtained from monomers selected from styrene, alpha-methyl styrene, vinyl toluene, acrylic and methacrylic esters, vinyl acetate and stearate, vinyl pyridine, vinyl chloride, butadiene and isoprene. Reactive monomers specified are acrylic, methacrylic, fumaric, itaconic, mesaconic and citraconic acids, monomethyl and monobutyl maleates, methylolated acrylamide and methacrylamide, acrylyl and methacrylyl isocyanates, glycidyl methacrylate, glycidyl allyl ether, vinyl piperidine, acrolein and allyl alcohol. The copolymer mixtures may be used in producing coatings which thermoset on heating. The examples describe following processes: (1) polymerizing in xylene with the aid of benzoyl peroxide (a) styrene, ethyl acrylate and acrylic acid, and (b) styrene, butyl methacrylate and glycidyl methacrylate, and then mixing the copolymer solutions and adding 2-butoxy ethanol and titanium dioxide thereto; (2) the copolymer solution 1(b) is mixed with a copolymer solution obtained by copolymerizing styrene, ethyl acrylate and acrylamide in solution in xylene/ethylene glycol monobutyl ether and then treating the copolymer with formaldehyde; (3) the formaldehyde-treated copolymer solution of (2) is mixed with a copolymer solution obtained by copolymerizing styrene, 2-ethylhexyl acrylate and acrylic acid in xylene in the presence of benzoyl peroxide, and then treating the copolymer with propylene oxide; and (4) the copolymer solution of 1(a) is mixed with a copolymer solution obtained by copolymerizing methyl methacrylate, ethyl acrylate and methacrylic acid in xylene in the presence of tertiary butyl hydroperoxide.
