    摘要： to obtain an amine-modified polymer. On blending an appropriate hardening agent with the amine-modified polymer, the composition cures very rapidly at ambient temperature. When pieces of wood or other materials are spread with the preferred adhesives employing the resin compositions of this invention and brought into contact with another wood or other surface the bond strength develops within minutes.

    where Y1 and Y2 are hydrogen or alkyl radicals having from 1 to 3 carbon atoms and Z is an integer from 0 to 2,

    AND A is

    WHERE:

    This invention describes resin products having particular utility as rapid curing adhesives for wood and other materials, and processes for making the resin compositions. The reaction products are made by reacting an aldehyde condensation polymer, such as a phenol-formaldehyde condensation polymer, with a primary aromatic amine having the formula:

    摘要： DISCLOSED ARE A LIQUID HARDENER FOR CONVERTING A PHENOL ALDEHYDE RESIN INTO AN ADHESIVE, AND A METHOD OF ITS MANUFACTURE. USE OF THIS HARDENER AVOIDS PROBLEMS ASSOCIATED WITH THE USE OF KNOWN POWDERED HARDENERS, SUCH AS CAKING OR LUMPING UNDER HUMID CONDITIONS, AND THE LONG AND COMPLICATED MIXING PROCEDURE REQUIRED TO BLEND POWDERED HARDENER WITH LIQUID RESIN. THE LIQUID HARDENER IS PREPARED BY COMGINING WATER, ALCOHOL, FORMALDEHYDE SOLUTION, FILLER, PROTECTIVE COLLOID, PYROGENIC SILICA AND WETTING AGENT IN APPROPRIATE PROPORTIONS.

    摘要： IMPROVED PHENOL-FORMALDEHYDE ADHESIVE RESINS SUITABLE FOR PLYWOOD MANUFACTURE ARE OBTAINED BY PREMIXING WITH AQUEOUS FORMALDEHYDE ABOUT 0.3-6.0 WEIGHT PERCENT OF HYDROXYETHYL CELLULOSE BASED ON FORMALDEHYDE AND THEREAFTER REACTING THE HYDROXYETHYL CELLULOSE FORMALDEHYDE SOLUTION WITH PHENOL IN THE PRESENCE OF ALKALI TO OBTAIN A THERMOSETTING PHENOL-FORMALDEHYDE RESOLE RESIN. WHEN FORMULATED AS A PLYWOOD GLUE, THIS MODIFIED PHENOL-FORMALDEHYDE RESIN PROVIDES AN ADHESIVE GLUE WITH ENHANCED TOLERANCE TO A WIDE VARIETY OF WOOD AND PRODUCTION VARIABLES INCLUDING ASSEMBLY TIME.
