BENZYLIC ETHER-TYPE PHENOLIC RESIN AND RESIN COMPOSITION CONTAINING SAME, AND BINDER AND CARBIDE EACH PRODUCED USING SAID RESIN OR SAID RESIN COMPOSITION

摘要

The purpose of the present invention is to provide: a benzylic ether-type phenolic resin which has a higher carbon residue content than those in the conventional phenolic resins and enables the advantageous production of a carbide having a high density and high oxidation resistance; a resin composition which contains the benzylic ether-type phenolic resin; and a carbide and a binder for use in the production of a carbon product or a fire-resistant product, each of which is produced using the benzylic ether-type phenolic resin or the resin composition and has excellent properties.A benzylic ether-type phenolic resin having a rate of substitution at ortho-position of 70% or more, wherein the proportion of the ratio of benzylic ether bond substitution is 10.0 to 40.0% and the proportion of the ratio of methylol group substitution is 13.0 to 40.0% when the sum total of the ratio of methylene bond substitution, the ratio of benzylic ether bond substation and the ratio of methylol group substitution, each of which can be determined as a content ratio of a substituent per 1 mole of a phenol core, is 100%.
