Abstract

PURPOSE: To prepare a resol-type phenolic resin having high molecular weight, long gel-time, and low odor, and useful as a raw material of laminate, by polymerizing a phenol compound with formaldehyde in the presence of a specific tert. amine and ammonia.
CONSTITUTION: Formaldehyde and a phenol compound are polymerized in the presence of a catalyst comprising a tert amine having a pKa of ≥10, e.g. triethylamine, and ammonia, until the molecular weight of the polymer reaches 280W380. The molar ratios of formaldehyde to the phenol, the tert amine to the ammonia, and the catalyst to the phenol, are 1 to 1W1.5, 1 to 1.2W1.5, and 0.02W0.05 to 1, respectively.
