    摘要: Ammeline-melamine-formaldehyde resins (AMFR) containing from 5-100% ammeline were synthesized by the polymerization of the sodium salt of ammeline, which must be made in advance, melamine, and formaldehyde in basic medium (pH = 9.2-10.0). In this copolymerization, it is possible to make uniform random AMFR resins with any mole ratio of ammeline salt to melamine. Preferably the AMFR resin will contain from 5-10% ammeline. As an "ionomer" or a "poly-electrolyte," both the solid and solution properties of these resins (such as melting temperature, solubility, solution stability, etc.) depended directly on the mole ratio of ammeline to melamine and formaldehyde, and/or on the pH value of the medium in which the AMFR resin was present. The pH value controlled the ammeline rings/ammeline's salt groups and also the ratio of unprotonated to protonated amino groups on both the melamine and ammeline rings. These polymers have different solubilities, cloud points and solution lifetimes (which depend on pH) than melamine-formaldehyde resins. AMFR systems containing from 5-10% ammeline are more flexible than MFR resins and exhibit different adhesion properties than MFR resins.

    摘要: Hemiacetals are prepared by reacting monohydric primary and secondary alcohols with adducts of acrolein and isocyanuric acid. The hemiacetals are useful for producing polymer compositions as polymerizing or crosslinking agents for polyfunctional compounds containing hemiacetal-reactive groups such as amines, amides, alcohols, thiols and oxiranes. The polymer compositions are useful in molding, laminating, coating and adhesive applications.
