Title: Improvements in or relating to modified methylol ethers
IPC: C08G12/40
Filed: 1956-12-17
Abstract: Urea and/or a derivative thereof and/or an aminotriazine is condensed with formaldehyde and one or more alcohols in the presence of one or more unsaturated carboxylic acids to produce modified methylol ethers useful for coating compositions. Particularly suitable acids are acrylic, methacrylic and crotonic. Polymerization of the acid is preferably avoided, e.g. by use of an inert atmosphere and absence of light, oxygen, peroxides and oxidation-reduction systems.  Up to 6 mols. of formaldehyde may be employed per mol. of urea or up to 9 mols. per mol. of aminotriazine.  Derivatives of urea and aminotriazines mentioned are thiourea, biuret, melamine, guanidine, cyanamide, dicyandiamide, hydrantoin, melam, melem, ammeline and ammelide. Using lower alcohols, e.g. methyl to butyl, ethylene glycol or 4-methoxybutyl alcohol, excess alcohol is usually employed to produce the product as a solution.  Higher ethers may be prepared from lower ethers by heating with a higher alcohol, e.g. heating a butyl ether prepared according to the invention with cetyl alcohol. If the alcohol used is water-miscible, water entrainers, e.g. petroleum ether or benzene, may be added to facilitate removal of water.  The products may be copolymerized with other polymerizable monomers, e.g. esters of acrylic or methacrylic acid, or styrene or polymerized in presence of polymers of other monomers.  The methylol ethers or their polymers may be prepared as emulsions or may be emulsified.  Films made from these emulsions may be stoved, e.g. at 140-150 DEG  C., and are flexible and water-resistant.  In the examples: (1) urea, formaldehyde, butanol and methacrylic acid are condensed together.  The resulting condensate is (a) copolymerized with benzoyl peroxide in turpentine and butanol with butyl methacrylate; (b) with a mixture of butyl methacrylate and butyl acrylate; (c) is copolymerized with benzoyl peroxide in ethyl acetate with a mixture of butyl and methyl methacrylate; (d) is copolymerized with benzoylperoxide in toluene with a mixture of styrene and methyl methacrylate; (e) is blended with butyl methacrylate to give a polymerizable solution; (f) is transetherified with cetyl alcohol. (2) Urea, formaldehyde, isopropanol and methacrylic acid are condensed in petroleum ether, and the product blended with methyl methacrylate to yield a polymerizable solution.  (3) Melamine, formaldehyde, butanol and methacrylic acid are condensed.  (4) Urea, formaldehyde, butanol, ethylene glycol and methacrylic acid are condensed together.  (5) Urea, melamine, formaldehyde, butanol and methacrylic acid are condensed together.  (6) The intermediate methylol ether of Example (1) is dissolved in butyl methacrylate and added to water containing ammonium persulphate and an emulsifier. The mixture is polymerized under nitrogen to yield a film-forming polymer dispersion.
