Abstract
Cationic amine-modified urea-formaldehyde resins are made by the acid condensation of a mixture of urea, formaldehyde and at least one polyalkylene polyamine of formula <FORM:0912902/IV(a)/1> x being one or more and n being 2 or 3, a watersoluble non-ionic aliphatic viscosity-lowering additive which is hydroxylated in aqueous solution being introduced into the reaction mixture at the point of incipient gelation thereof, and the reaction being then continued until the point of incipient gelation is again reached. Viscosity-lowering additives mentioned are formaldehyde, paraldehyde, methyl, ethyl, n-propyl, iso-propyl, or tert.-butyl alcohol, ethylene glycol, glycerine, diethylene glycol, triethylene glycol, glucose, or furfuryl alcohol. Suitable polyamines mentioned are triethylene tetramine, tetraethylene pentamine. The reaction medium may be rendered acid with diglycolic, maleic, oxalic, phthalic, acetic, phosphoric, hydrochloric or sulphuric acid. In a typical Example (1) Ammonium sulphate, urea, triethylene tetramine and 37% formaldehyde were refluxed with stirring for 10-15 minutes. Diglycolic acid was added and heating continued to the point of incipient gelation. Further formaldehyde was added and heating continued until the mixture again began to gel. This process was repeated twice and the reaction mixture was then neutralized, and diluted with water to 31% solids. The resin syrups are useful for addition to paper pulp in the beater to increase the wet strength of the treated paper.
