    Abstract: 1,255,546. Oxymethylene polymer composition; amide-containing polycondensates. BADISCHE ANILIN - & SODA-FABRIK A.G. 24 April, 1969 [25 April, 1968], No. 20924/69. Headings C3P and C3R. Oxymethylene polymers are heat stabilized by adding up to 5% of a polycondensate obtained by reacting in an acid aqueous medium at 40‹ to 100‹ C. (A) a diamide of a nitrogen-free dicarboxylic acid; (B) an amide having at least two carboxylic amide groups and at least one basic secondary or tertiary nitrogen atom; (C) an N,N 1 -alkylene- or N,N 1 -hydroxy, alkyl or alkoxy substituted alkyleneurea, or an N,N 1 -disubstituted urea wherein the substituents are alkyl, aryl or aralkyl ; and (D) formaldehyde or a formaldehyde yielding substance or an N- methylol compound of components (A) or (C). An antioxidant may also be included. Formaldehyde or trioxan polymers may be stabilized and in examples, various condensates of isophthalimide, nitrilo - trilactamide, N,N 1 - ethylene or propylene urea and formaldehyde are prepared and mixed with a trioxan-dioxolan copolymer and 2,2 1 -methylene-bis-(4-methyl-6 (t-butylphenol).

    Abstract: Novel bis-aziridine glycols of the general formula in which R1, R2, R3 and R4 each denote a hydrogen atom or an alkyl group, e.g. N,N1 (1,2 - dihydroxyethylene) - bis - ethylenimine, N,N1 - (1,2 - dihydroxyethylene) - bis - 2 - methylethylenimine, and N,N1-(1,2-dihydroxy-ethylene) - bis - 2 - ethylethylenimine, are made by the reaction of an aziridine having the general formula with glyoxal at a temperature of from - 10 DEG to +80 DEG C. in the presence of water, preferably in an amount of 0.5 to 80% by weight with reference to the whole reaction mixture. An organic solvent and/or suspension agent, for example a lower alkanol of 1 to 4 carbon atoms, a C3-C6 aliphatic ketone, cyclic 5 to 6 membered ethers for example dioxane, tetrahydrofuran, or 1,3-dimethyl-dioxane, N-alkyl substituted pyrrolidones, for example N-methyl or ethyl pyrrolidone, may also be present. The products are stated to be useful additives in printing paste used to print fabric, for example, cotton (see Division D1).ALSO:Printing paste compositions used to print fabrics, e.g. cotton, give improved laundering resistance by incorporating therein a bis aziridine glycol of the general formula: wherein R1, R2, R3 and R4 each denote a hydrogen atom or an alkyl group. In an example N,N1 (1, 2-dihydroxy-ethylene) bis-ethyleneimine is added to a print paste comprising copper phthalocyanine, a thickener emulsion of the oil-in-water type, triethanolamine and an aqueous dispersion of a co-polymer of butyl acrylate, styrene and acrylic acid and the paste used to print cotton cloth which is then dried at 40-60 DEG C and after treated at 180-200 DEG C for 3 to 5 minutes.
