  • Liquid aminoplast polyfunctional resin compositions
    Patent number: 4031057
    Abstract: Thermosettable liquid resin compositions comprising a reactive polymer and an N,N'-bis(alkoxymethyl)uron such as N,N'-bis(butoxymethyl)uron.

The uron ether is employed as a cosolvent for the polymer whereby the solution may be applied as a coating without the need for significant amounts of conventional solvents. Interaction between the polymer and the uron ether promoted by heat in the presence of acid catalyst shifts the role of the uron ether to that of a crosslinking agent for the polymer.
