Procedure
Separately, a 18%-melamine aqueous dilution liquid at 32.9 kg/h and formalin (adjusted to ph 8.0 by addition of 20%-triethanolamine aqueous solution) (12) at 19.1 kg/h were supplied to a resin prepolymer reaction vessel (15) and were caused to reside therein for 35 min. at 50° C. under stirring to continuously produce a melamine resin prepolymer (formaldehyde/melamine=4 (by mol)) liquid.
