LATENT PHENOL RESIN, METHOD FOR PRODUCING THE SAME AND METHOD FOR PRODUCING PHENOL RESIN BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new latent phenol resin and to provide a method for producing the latent phenol resin by a simple method and to provide a method for producing the phenol resin by using the method.;SOLUTION: The latent phenol resin is represented by general formula (1) (wherein R₁ is a 1-10C alkyl group, alkenyl group, an acyl group or a 3-12C cycloalkyl group; R₂ is hydrogen, a 1-10C alkyl group, an aromatic hydrocarbon group or an alkoxy group; R₃ is hydrogen, a 1-10C alkyl group, an alkenyl group, an aromatic hydrocarbon group or a 3-12C cycloalkyl group; R₄ is hydrogen, a 1-11C hydroxyalkyl group, a hydroxyalkenyl group, a hydroxyaromatic hydrocarbon group or a 4-13C hydroxycycloalkyl group; l is an integer of 1-3; m is an integer of 1-3; n is an integer of 0-20,000; R₁, R₂, R₃ and R₄ may be the same as or different from each other).;COPYRIGHT: (C)2004,JPO&NCIPI
