  • Patent number: 5317050
    Abstract: Compositions containing an aryl phosphite and water to hydrolyze the aryl phosphite provide controlled and extended work time when used as hardening agents for the ambient temperature hardening of phenolic resins and for rapid hardening of such resins at modestly elevated temperatures. Pre-solvolysis with small quantities of water, alkanols of 1 to 4 carbon atoms or alkylene glycols of 2 to 4 carbon atoms improve compatibility of trisubstituted phosphites with the resin. Pre-hydrolysis of the phosphites as well as addition of furfuryl alcohol or alkylene glycols of 2 to 4 carbon atoms accelerate the hardening (curing) of the resin. Various compounds such as: carboxylic acid amides, urea, dicyandiamide, N-methylolated amides, N-alkyl 2-pyrrolidinones having 1 to 4 carbon atoms in the alkyl group, those having an internal epoxide group, alkanols, and Schiff bases retard the ambient temperature hardening of the resin with the aryl phosphite hardening agents.
