Abstract

Polyethermelamines are prepared by reaction of at least one mono- or poly-hemiformal of a polyhydroxyl compound with melamine in the presence of an acid or basic catalyst. The initial hemiformal may be mixed with at least one hemiformal derived from a monohydroxyl compound. Some of the melamine may be replaced by urea or thiourea, the amount of urea being from 5 to 95% by wt. of melamine. Condensation may take place at 30-95 DEG C., followed by cure at > 100 DEG C. From 0.001 to 5% (based on the melamine) of acid or basic catalyst may be employed. Reaction may take place in a solvent (e.g. water, alcohols, dimethylformamide and benzene). Most of the examples relate to hemiformals of polyhydric alcohols, but those derived from polyhydric phenols (e.g. resorcinol) may also be used.
