Title: NOVOLAC TYPE PHENOLIC RESIN, RESIN COMPOSITION AND METHOD FOR PRODUCING NOVOLAC TYPE PHENOLIC RESIN
Abstract:
This novolac type phenolic resin is a reaction product that is obtained by reacting a lignin that has an aliphatic hydroxyl group in each molecule, a phenol and an aldehyde in the presence of an acid catalyst; and the content ratio of the aliphatic hydroxyl group in the lignin is from 0.5% by mass to 7.0% by mass (inclusive) relative to the total mass of the lignin.
