Abstract

PURPOSE: To produce a titled binder in the form of liquid contg. no solvent insoluble resins by causing urea and aldehydes to react in the presence of an alkaline catalyst thence adding furfuryl alcohol thereto and causing these again to react in an acidic pH region.
CONSTITUTION: A urea resin is produced by using 1.5W2.5mol aldehydes basing on 1mol urea, and causing these to react in the presence of an alkaline catalyst. Then, 0.3W15mol furfuryl alcohol and an acid to this resin liquid, and these are caused to react again under the conditions of 3.5W5.0pH. After the reaction, the liquid is neutralized with aqueous ammonia or the like, thence the water in the reacting liquid is removed by distillation or the like, whereby the urea modified furan resin in the form of liquid contg. no insoluble matter at all is produced. This resin is used as a binder for self-curing molds.
