Abstract

PURPOSE:To prepare the titled resin by reaction of melamine with formaldehyde, then carrying out co-condensation with both guanamine and toluenesulfonamide fellowed by incorporating the resulting system with oxyethylene-oxypropylene block copolymer. CONSTITUTION:1 mole of melamine is made to react with (1) 1.8-3.0 moles of fomaldelyde at a PH of 8-12, followed by adding (2) guanamine and toluenesulfonamide in a total amount of 0.2-1.5 moles so that the woler ratio of the toluene-sulfoamide to the guanamine is 0.3-2.5. After that, the resulfing system is subjected to co-condensation at a PH of 5-11 followed by adding (3) 20-50 parts by wt., based on the system just obtained, of oxyethylene-oxypropylene block copolymer of a molecular weight of 3,000-15,000. The mixture thus obtained is agitated, then cooled to make a strup-like liquid resin. The decorative laminates manufactured from the above liquid resin are greatly improved in secondary processability with keeping their inherent characteristic.
