摘要： A substitute for amino and phenolic resins is disclosed. It is used in the polycondensation of such resins based on formaldehyde for bonding water penetrable cellulosic particles. The substitute comprises an aqueous solution of(a) either at least one aldehyde together with at least one amide and/or together with at least one phenol, or a non-resinous condensation product of formaldehyde and urea, and(b) a sugar or a sugar derivative or their byproducts or a starch or its degradation products or a mixture thereof, and/or(c) a raw and/or treated lignosulfonate.This substitute also reduces the free formaldehyde of the resulting board without impairing the other properties thereof.

摘要： A process for preparing a urea-formaldehyde base resin having a F/U molar ratio of 1.0:1-1.2:1, that is hydrolytically stable, which comprises adjusting a formaldehyde solution to a pH of 0.5-2.5, slowly charging urea to said formaldehyde solution while maintaining the temperature at 40.degree.-70.degree. C., neutralizing the reaction mixture after obtaining a Gardner viscosity in the range of T+-V+, then adding the final charge of urea and permitting equilibration.

摘要： 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 aldehude condensation polymer containing reactive alkylol groups, such as a phenol-formaldehyde condensation polymer, with di-substitued bis-aryl amine having the formula:

WHERE R and R'' are alkoxy, amino, hydrogen, hydroxyl, nitro, carboxyl or C1 to C4 alkyl AND X is

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 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 surface the bond strength develops within minutes. The durability, strength and flexibility of the adhesives of this invention under adverse weathering conditions are excellent.
