ABSTRACT:
Electrolyte-free etherified methylolaminotriazines are directly prepared by reacting together in the absence of electrolyte, the aminotriazine, formaldehyde and certain ether-alcohols. When the formaldehyde to aminotriazine mol ratio is sufficiently high and the etherification sufficiently extensive, the resulting products are particularly desirable in that they are quite stable and thermoset to exceptionally elastic, cured products having high electrical, moisture, and temperature resistance.
