SEEN TO PROMOTE AMINOPLATION DISPERSIONS AND THEIR USE AS REACTION COMPONENTS FOR ISOCYANATES IN THE MANUFACTURING OF POLYURETAN PLATES

摘要

The instant invention is directed to a process for the production of dispersions of aminoplast condensates in organic polyhydroxyl compounds by the oligo-condensation or polycondensation of substances capable of aminoplast formation, in said organic polyhydroxyl compounds, the improvement wherein said dispersions are reacted at from about -5 DEG C. to about 180 DEG C. with an amine compound selected from the group consisting of: (a) organic aliphatic or cycloaliphatic mono or polyamines containing at least one primary or secondary amine group, and which are gaseous or liquid at room temperature, and (b) organic alkyl hydrazines containing at least one primary or secondary amine group and which are gaseous or liquid at room temperature.
