Abstract: PURPOSE:A resin resulting from the reaction between a specific aralkyl compound and phenol is made to react with an alkaline earth metal oxide or other compounds at high temperatures to produce the titled modified resin with high heat resistance, wearing resistance, chemical resistance and electrical properties. CONSTITUTION:An aralkyl compound of the formula (R is 1-6C alkyl, 2-6C acyl; n is 1,2), preferably alpha,alpha'-dimethoxy-p-xylene, is made to react with a phenol, preferably at a molar ratio of 1.3-3 at 70-200 deg.C. The resultant resin is mixed with an oxide or hydroxide and/or carbonate of an alkaline earth metal at a temperature higher than the softening point of the resin to effect the reaction, thus producing the objective resin.
