Abstract

PURPOSE: To obtain in high yield a resol resin with high penetrability into base materials and moderate cure rate by the use of a catalyst consisting a secondary and a tertiary amines in a specific ratio in the reaction between a phenol and a formaldehyde source.
CONSTITUTION: The objective resol resin can be obtained by the reaction between a phenol and a highly-concentrated formaldehyde source such as formalin, paraformaldehyde, etc., in the presence of a catalyst consisting of a secondary amine such as dimethylamine, diethylamine, and a tertiary amine such as triethylamine in an N-molar ratio teriary/secondary of 1.9W7.8.
