Abstract
537,009. Polyamide-aldehyde condensation products ; treated fabrics ; dyeing. DU PONT DE NEMOURS & CO., E.I. Sept. 29, 1939, No. 26886. Convention date, Sept. 30, 1938. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] Synthetic resins are prepared by heating a polyamide-forming material as described in Specifications 461,236, 461,237 and 474,999 (a mixture of diamine and dicarboxylic. acid, a diamine dibasic acid salt or a monoaminomonocarbonylic amine) with a urea to form a low molecular weight polymer and treating the condensate with an aldehyde, the quantity of urea employed being at least 0.5 molecules per molecule of polymethylene di ammonium salt present or potentially present in the polyamide. The reaction with aldehyde is preferably effected in the presence of an alcohol. The term " urea includes urea and its equivalents in resin-formation with aldehydes such as thiourea, ammonium isocyanate, ammonium isothiocyanate, biuret, cyanamide, guanidine, guanidine isocyanate, guanidine carbonate, ammonium carbonate, and dicyanadiamide. Suitable diamines include tetra-, penta-, hexa-, and octamethylene diamine, p-xylylenediamine, triglycoldiamine, diaminoisopropanol and diethylenetriamine; suitable acids include glutaric, adipic, pimelic, suberic, lutidinic, sebacic, methyladipic, p-phenylenediacetic, terephthalic and isophthalic acids ; suitable aminoacids or lactams include 6-aminocaproic, 9-aminonon- anoic and 11-aminoundecanoic acids and caprolactam ; the diamines and dicarboxylic acids are preferably used as salts. In examples hexamethylene diammonium adipate and urea are heated and the product reacted (1) with a solution of urea in isobutanol and aqueous formaldehyde, (2) with a solution of aqueous formaldehyde in isobutanol or methanol, (4) with aqueous formaldehyde ; (7) hexamethylene diammonium adipate and urea are heated in the presence of m-cresol, the product being reacted with aqueous formaldehyde in the presence of ethanol; (8) hexamethylenediammonium adipate is heated with urea and the product, after refluxing with isobutanol is reacted with formaldehyde; (10) decamethylenediammonium sebacate is heated with urea and the product heated with a solution of aqueous formaldehyde in isobutanol; (11) hexamethylenediammonium isophthalate is heated with urea and the product heated with a solution of aqueous formaldehyde in isobutanol. The products may be used in the manufacture of coating compositions, moulding powders and films which are readily dyed by silk or wool dyes. Fabrics impregnated with dilute solutions of the resin and baked are rendered crease-resistant and water-repellent and their affinity for silk and wool dyes is increased. The resins may be plasticized by castor oil modified alkyl resins. They may be used as top-coatings over nitro-cellulose coated fabrics. U.S.A. Specifications 2,071,250 and 2,130,948 are referred to.
