    摘要: 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: ##SPC1##WhereX.sub.1 is --NH.sub.2 --CH.sub.2 NH.sub.2 ;X.sub.2 is --X.sub.1 --OH--alkoxy;X.sub.3 is -X.sub.1 COOH NHCOCH.sub.3 NO.sub.2 OH C.sub.1 to C.sub.5 alkyl H -halogen halogenated alkyl alkoxy X.sub.4 is C.sub.1 to C.sub.4 alkyl, --H--aryl; andA is ##EQU1## where Y.sub.1 and Y.sub.2 are hydrogen or alkyl radicals having from 1 to 3 carbon atoms and Z is an integer from 0 to 2,--SO.sub.2 ----NH----O----S---- C----S--S----N=N--, 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.
