ABSTRACT:
Novel resins are disclosed that are the reaction products of an aldehyde and an aromatic alcohol mixture of naphthol, preferably 1-naphthol, and a phenol. The molar ratio of the naphthol to the phenol in the reaction mixture can vary from about 20 to 1 to 1 to 20. The resins are formed by condensing the aldehyde with the aromatic alcohol mixture in the presence of an acid catalyst where the molar ratio of the aromatic alcohol to aldehyde is less than 1. The resins of the invention are characterized by melt temperature higher than the melt temperatures of conventional novolak resins.
