Abstract: 1,137,925. Copolymers of etherified methylol- (meth)-acrylamide. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 April, 1966 [10 April, 1965; 26 May, 1965], No. 15501/66. Heading C3P. In a multi-stage process for preparing derivatives of amide copolymers (A) 0À9-1À2 moles of (meth)-acrylamide, 0À9-1À2 moles of paraformaldehyde (calculated as monomer), at least 0À9 moles of an (oxa)-alkanol having up to 8 carbon atoms and 0À001-0À5 moles of a tertiary aliphatic or cycloaliphatic monoamine having up to 12 carbon atoms are reacted at 50-100‹ C.; (B) then at least 101 equivalent per cent, based on said monoamine, of an α,#-ethylenically unsaturated mono- or di-basic carboxylic acid and/or an (oxa)-alkyl half-ester of such a dibasic acid having up to 9 carbon atoms in the (oxa)-alkyl radical is added and the mixture kept at 80-140‹ C.; (C) then any remainder of the said carboxylic acid or half-ester, and an (oxa)-alkyl ester of (meth)-acrylic acid having up to 20 carbon atoms in the (oxa)-alkyl radical and/or an (alkyl)-vinyl benzene having up to 12 carbon atoms and, if desired, other comonomer are added and copolymerization is carried out using an aliphatic or cycloaliphatic azo compound or an organic peroxide having a half-life of 0À1-30 hours at 85-110‹ C. as polymerization initiator. Polymerization is generally effected in an organic solvent which may be an excess of the (oxa)-alkanol used in step (A) or benzene or an alkyl benzene. In step (A) an oxygen-containing atmosphere is used and in step (B) a polymerization inhibitor is desirably included, e.g. phenothiazine, hydroquinone, methylene blue, nitrosophenol or mdinitrobenzene. The initiator used in step (C) may be azodiisobutyronitrile, azodiisobutyramide, azodicyclohexylcarbonitrile, cumene hydroperoxide, dibenzoyl peroxide, dilauroyl peroxide, t - butyl permaleate, t - butyl hydroperoxide, 2,2 - bis - (t - butyl peroxy)- butane or t-butyl perbenzoate; the initiator may be added continuously during polymerization. A regulator, e.g. t-dodecyl mercaptan, may be included in the polymerization reaction. In the examples, the following monomers are used: acrylamide, maleic acid, acrylic acid, styrene, 1,4-butane-diol monoacrylate and also, in some cases, 2-ethyl hexyl acrylate; the (oxa)-alkanol being n-butanol and the amine being N,N - dimethyl - (# - hydroxyethyl)- amine. The polymers obtained in the invention are useful in coating compositions, stoving lacquers, impregnants and adhesives.

Abstract: 1,161,095. Coatings. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 Oct., 1966 [26 Oct., 1965], No. 47815/66. Heading B2K. [Also in Divisions C3, D1 and D2] Hardboard is coated with an organic solvent solution, containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, styrene, 2-ethylhexyl acrylate, N-butoxymethylmethacrylamide, and acrylic acid, the coating then being dried and hardened by heating. An aqueous dispersion containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate with styrene may be applied to hardboard. Steel and glass sheets are coated may be with an organic solvent solution containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, 2-ethylhexyl acrylate and styrene.

Abstract: A stoving lacquer comprises at least one organic solvent and a mixture containing (i) at least 30 wt. per cent of an alkyd resin from (a) a C8- 20 aliphatic monocarboxylic acid; (b) a mixture of C4- 10 dicarboxylic acids, 1 to 80% being, 1,2-dihydrophthalic acid; (c) a C3- 10 higher than dihydric alcohol; and optionally (d) a C4- 10 higher than dicarboxylic acid; and (e) a C2- 10 dihydric alcohol, and (ii) up to 70% of an "aminoplast resin." The term "aminoplast resin" is defined as including copolymers of N-alkoxymethyl amides of ethylenically unsaturated carboxylic acids as well as conventional etherified urea- or melamine-formaldehyde condensates but no specific example of the use of such co-polymers is given. The lacquers may include curing catalysts, flow promoters and other binders, e.g. epoxy resins. They may be used to lacquer metals, e.g. sheet metals. In the example the solvent is xylene and TiO2 pigment is included.ALSO:A stoving lacquer comprises an organic solvent and a mixture containing (i) at least 30 wt. % of an alkyd resin from (a) a C8-20 monocarboxylic acid; (b) a mixture of C4-10 dicarboxylic acids, 1 to 80% being 1,2 dihydrophthalic acid; (c) a C3-10 higher than dihydric alcohol; and optionally (d) a C4-10 higher than di-carboxylic acid; and (e) a C2-10 dihydric alcohol, and (ii) up to 70% of an "aminoplast resin".
