  • Patent number: 5424390
    Abstract: A process of producing an aqueous solution of a sulfonated melamine-formaldehyde resin. The process comprises condensing melamine and formaldehyde or a precursor of formaldehyde (e.g. paraformaldehyde) in an aqueous mixture having a pH in the range of 8-10 to form a reaction mixture containing a condensation product of melamine and formaldehyde. The condensation product is then reacted in an aqueous mixture having a pH of 8-10, preferably 8-9, with a sulfonating agent to produce a mixture containing a sulfonated condensation product. Finally, polymerizing the said sulfonated condensation product in an aqueous mixture having a pH of 5-7 to form a resin solution. In the process, at least one of the sulfonation step and the polymerizing step is carried out under superatmospheric pressure (generally 5 to 70 p.s.i.) and at an elevated temperature of, in the case of the sulfonating step, C. for a time of 1 to 5 hours or of, in the case of the polymerizing step, C.
