Abstract
PURPOSE: To obtain a casting resin having improved performance with low unreacted phenol and aldehyde contents, by reacting a phenol with an aldehyde and furfuryl alcohol in the presence of an alkali calayst, and then with a urea derivative.
CONSTITUTION: One mole of a phenol is reacted with 1.5W25 moles, preferably 1.6W20 moles of an aldehyde in the presence of an alkali catalyst at a relative by low temperature of 50W70°C. 100 parts by wt. of the reaction product thus obtained is then reacted with 1W10 parts by wt., preferably 2W5 parts by wt. by a urea derivative or its mixture. Cresol or 2,2-bis(p-hydroxyphenyl) propane may be cited as the phenol. Urea modified with an amino compound or polyhydric alcohol may be cited as the urea derivative.
