Title: Process for the preparation of synthetic resin-modified n-alkoxymethyl polyamide compositions
IPC: C08G69/50
Filed: 1945-08-13
Abstract: Synthetic resin - modified N - alkoxymethyl polyamides are prepared by reacting in the presence of an oxygen-containing acid catalyst a synthetic linear polyamide having hydrogen-bearing carbonamide groups with an aliphatic or substituted aliphatic alcohol and formaldehyde, the formaldehyde being in excess of that theoretical amount required to react with all the amide groups of the synthetic linear polyamide and then reacting the resulting mixture with a formaldehyde reactive resin-forming material.  The synthetic linear polyamide is of the type described in Specification 461,236 and U.S.A.  Specifications 2,071,250 and 2,130,948, and the acid catalyst is for example formic, trimethyl acetic, chloracetic, maleic, benzoic, hydroxyacetic, paratoluenesulphonic or the acids of phosphorus. The formaldehyde-reactive resin forming material may be urea, thiourea, melamine, phenols, but preferably phenol itself and phenols having at least three nuclear hydrogen atoms such as resorcinol or cresol, sulphonamides and protein such as casein, zein and soybean protein, the preferred materials being those which react with formaldehyde to form heat-hardening resins.  The proportions of reactants should be preferably 1 part of polyamide, 0.75 to 12.5 parts by weight of alcohol and 0.5 to 5.0 parts by weight of formaldehyde. Formaldehyde-liberating substances may be used instead of formaldehyde.  Curing catalysts, such as maleic acid, phosphoric acid, p-toluene sulphonic acid, zinc chloride, sodium carbonate or potassium hydroxide may be added to the resin-modified N-alkoxymethyl polyamides before they are applied as bonding materials.  In the examples: (1) a solution of N-methoxymethyl polyhexamethylene adipamide and formaldehyde in aqueous methanol is reacted with urea in the presence of caustic soda and the resulting solution used to make plywood, (2) resorcinol and the maleic acid were added to the N-alkoxymethyl polyamide solution, (3) meta cresol and then maleic acid were added to the polyamide solution, (4) zein in alcoholic solution and then maleic acid were added to the polyamide solution. Specifications 534,698, 573,482 and 596,087 also are referred to.

Abstract: 358,149. Compound transparent sheets. DEHN, F. B., 103, Kingsway, London.-(Libbey-Owens-Ford Glass Co. ; 608, Madison Avenue, Toledo, Ohio, U.S.A.) July 11, 1930, No. 21099. [Class 140.] Relates to a process of producing laminated glass wherein one or more layers of a non-brittle cellulose composition is or are secured to the glass sheets by a gelatine solution produced without water. According to the invention, the gelatine solution also contains a material which is capable of dissolving a cellulose composition without the use of water. Such a solution is obtained, according to one process, by dissolving dry gelatine in a mixture of polyglycols and polyhydric alcohols. Thus 20 per cent by weight of granulated gelatine is reacted with glycerol at a temperature of 100‹ C. until a homogeneous, gel is produced. 20 per cent by weight of this mixture is then dissolved in diethylene glycol, and the resultant mixture, which is liquid at slightly elevated temperatures, is applied to the sheets. In another method, one gram of calcium chloride is dissolved in 80 grams of diethylene glycol. To this solution is added 20 grams of glycerol, followed by 40 grams of dry gelatine. The latter is added slowly with constant stirring, the mixture being maintained in the neighbourhood of 90‹ C. Diethylene glycol is added to make up one kilogram of the adhesive. Barium chloride, manganous or cerium chloride may be used in place of the calcium chloride. After applying the solution and arranging the sheets, the resultant " sandwich " is preferably subjected to a preliminary pressing operation before being transferred to the autoclave.
