Abstract
PURPOSE: To prepare a phenolic resin having excellent plasticity, and useful for the core material of a melamine-surfaced decorative laminate, by the polycondensation of a phenolic compound with formaldehyde in the presence of an alkaline catalyst and methylpentanetriol.
CONSTITUTION: A phenolic resin is prepared by heating and refluxing a phenolic compound (1 mole) such as phenol, cresol, etc. with formaldehyde 1.2W2.0 moles) in the presence of 3-methylpentane-1,3,5-triol (0.04W0.18 mole) at pH7.5-12.0. The triol is pref. added prior to the completion of the reflux, addition after the reaction is also effective.
