| titleOfInvention | Improvements in and relating to resinous condensation products |
| abstract | Resinous condensation products are prepared by heating together an aldehyde and 2-ureido-4,6-diamino-1,3,5-triazine. The reaction may be carried out in the presence of ketones, ureas such as those described in Specification 554,195, amides, sulphonamides, triazines such as those described in Specification 1458/42, as open to inspection under Sect. 91, phenols, aminophenols, nitriles, alcohols and amines. Hardening may be accelerated by the use of the catalysts described in Specifications 9244/41 and 10917/41, both as open to inspection under Sect. 91. Aldehydes specified are formaldehyde, propionaldehyde, hexamethylenetetramine, acetaldehyde, propionaldehyde, butyraldehyde, methacrolein, crotonaldehyde, benzaldehyde, furfural, aldehyde-addition products such as methylol-ureas, methylol-amides and methylol-aminotriazines. There may be added hydrolized wood products, lignin, water-soluble cellulose derivatives, shellac, rosin, polyvinyl esters, ethers and acetals, protein-, aminotriazole-, aminodiazole-, urea-, aniline-, phenol-, and aminotriazine-aldehyde resins, alkyd resins, furfural condensation products, dyes, pigments, plasticizers, mould lubricants, e.g. zinc stearate, fillers, e.g. a -cellulose, wood flour, glass fibres, asbestos, mineral wool, mica and cloth cuttings. The product may be used in making moulding compositions, coating compositions, abrasive articles, laminated articles and for impregnating textiles. Examples describe heating together (2), (3) and (4) the triazine derivative, aqueous formaldehyde and urea, thiourea or melamine, (5) the triazine derivative and dimethylol urea, and (6) the triazine derivative, aqueous formaldehyde and butyl alcohol. 2 - ureido - 4,6 - diamino - 1,3,5 - triazine may be prepared by stirring together 2-chloro-4,6-diamino-1,3,5-triazine and sodium urea in ether or benzene, at or below room temperature, filtering off the product and washing free from sodium chloride. The Specification as open to inspection under Sect. 91 describes also the use of triazine derivatives corresponding to the general formula:- <FORM:0561077/IV/1> or salts thereof in which n is 1, 2 or 3, Y is oxygen or sulphur, and R is hydrogen or a monovalent hydrocarbon or halohydrocarbon radical. Derivatives of the asymmetrical and vicinal triazines are also referred to. This subject-matter does not appear in the Specification as accepted. |
