Rapid curing phenolic-aldehyde resin composition polymer modified with a heterocyclic nitrogen-containing compound

Abstract

Abstract DESCRIBED HEREIN ARE RESIN PRODUCTS HAVING PARTICULAR UTILITY AS RAPID CURING ADHESIVES FOR WOOD AND OTHER MATERIALS, AND PROCESSES FOR MAKING THE RESIN COMPOSITIONS, THE PRODUCTS ARE MADE BY REACTING ALKYLOL GROUPS, SUCH AS TION POLYMER CONTAINING REACTIVE ALKOYLOL GROUPS, SUCH AS A PHENOL-FORMALDEHYDE CONDENSATION POLYMER, WITH A HETEROCYCLIC NITROGEN-CONTAINING COMPOUND TO OBTAIN AN AMINE-MODIFIED POLYMER. WHEN THE RESULTING REACTION PRODUCT IS BLENDED WITH AN APPROPRIATE CURING AGENT, SUCH AS AN ALDEHYDE, THE COMPOSITIONS CURE VERY RAPIDLY AT AMBEINT TEMPERATURE. WHEN PIECES OF WOOD OR OTHER MATERIALS ARE SPREAD WITH THE PREFERRED ADHESIVE EMPLOYING THE RESIN COMPOSITIONS OF THIS INVENTION AND BROUGHT INTO CONTACT WITH ANOTHER WOOD SURFACE THE BOND STRENGTH DEVELOPS WITHIN MINUTES. THE DURABILITY, STRENGHT AND FLEXIBILITY OF THE ADHESIVES OF THIS INVENTION UNDER ADVERSE WEATHERING CONDITIONS ARE EXCELLENT.
