Abstract: 1,174,462. Seaming non-metallic sheet material. BADISCHE ANILIN- & SODAFABRIK A.G. 22 Feb., 1967 [23 Feb., 1966], No. 8430/67. Heading B5K. [Also in Division C3] Leather-leather, leather-rubber and woodwood bonds are formed by applying a coating of a hot-melt adhesive to 2 cm. wide strips of the respective materials and sticking them together, the adhesive being selected from (a) a graft polymer of n-butyl acrylate and styrene on an n-butyl acrylate/styrene copolymer, or a mixture of said graft polymer with an n-butyl acrylate/styrene copolymer and/or a cyclohexanone resin, or with Russian balsam, (b) a graft polymer of 2-ethylhexyl acrylate, or nbutyl acrylate, and styrene on polystyrene, or a mixture thereof with Russian balsam (c) a graft polymer of n-butyl acrylate, dodecyl acrylate, butanediol monoacrylate and styrene on an n-butyl acrylate/styrene copolymer or (d) a graft polymer of n-butyl acrylate and styrene on an n-butyl acrylate/styrene/acrylic acid copolymer, or a mixture thereof with colophony.

Abstract: A process for the preparation of curable etherified aminoplast resins based on urea/ aldehyde polycondensates, and the preparation of surface coating resins. Urea is first reacted with an .alpha.,.alpha.-dialkylaldehyde, as much as 50 mol% of which may be replaced by formaldehyde, in a molar ratio urea/aldehyde of about 1-2, at from 50 to 120.degree.C, in the presence of an acid and in the presence or absence of an alcohol or of other organic solvents, and the 2-oxohexahydropyrimidine derivative obtained in this cyclocondensation is then condensed with formaldehyde in the presence of one or more alcohols and an acid. These aminoplast resins are useful as both acidcurable resins and as resins for baking finishes.
