POLYMERIC COMPOSITIONS THAT CONTAIN A PHENOLIC RESIN CONTAINING REPEATING UNITS HAVING THE FORMULA: -CH(-R)-(2-HO,R''-1,3-PHENYLENE)-, -CH(-R)-(2-HO,HO,R''-1, 3-PHENYLENE)-, -SN-(2-HO,R''-1,3-PHENYLENE)-, AND -SN-(2- HO,HO,R''-1,3-PHENYLENE)- OR MIXTURES THEREOF WHEREIN R AND R'' ARE HYDROGEN OR ALKYL, CYCLOALKYL OR ARYL RADICALS HAVING FROM 1 TO 24 CARBON ATOMS, N IS 1 OR 2 AND THE AVERAGE NUMBER OF REPEATING UNITS IN SAID POLYMERIC COMPOUND IS AT LEAST 3, AND A METAL DEACTIVATOR HAVE UNEXPECTEDLY HIGH THERMAL OXIDATIVE STABILITY AFTER EXTRACTION BY VISCOUS LIQUIDS. THESE COMPOSITIONS ARE PARTICULARLY USEFUL IN THE INSULATION OF ELECTRICAL CABLES WHICH ARE UTILIZED IN ENVIRONMENTS LIKELY TO CAUSE EXTRACTION OF STABILIZER SYSTEMS. |
