    Abstract: The invention relates to a method for producing highly-branched melamine polymers, according to which melamine with 1.5 to 4 mol of one or several diamines or polyamines per mol of melamine, said diamines or polyamines having at least two primary amino groups, is reacted in the presence of an acidic catalyst. According to the invention, up to 25 mol % of the diamines or polyamines can have three or more primary amino groups and up to 50 mol % of the diamines or polyamines can be substituted by amines with only one primary amino group.
