Abstract
This invention provides a thermosetting resin and a method for producing the same, in which 5% to 95% by weight of an aminoplast resin and 5% to 95% by weight of a polyalkylene glycol are subjected to a condensation reaction under alkaline conditions, the resulting reaction product is methoxylated with methanol, and pH of the methoxylated product is controlled in a range from 10 to 11. The thermosetting resin for impregnation of resins or for use in building materials obtained according to the invention is highly stable, can be diluted with water, has excellent workability, stiffness, chemical resistance, water resistance, moisture resistant strength, and adhesion in water, exhibits improved brittleness and has satisfactory flexibility and impact resistance.
