A POLYESTER RESIN INSULATING COMPOSITION CONSISTING ESSENTIALLY OF A BLENDED SOLUTION OF (A) A HIGHLY FUNCTIONAL POLYESTER DERIVED BY HEATING TO ESTERIFY A MIXTURE OF (1) FROM ABOUT 40 TO 45 EQUIVALENT PERCENT OF AT LEAST ONE DICARBOXYLIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF ISOPHTHALIC ACID AND THE 1 TO 4 CARBON ATOM DIALKYL ESTERS OF ISPHTHALIC AND TEREPHTHALIC ACIDS AND (2) FROM ABOUT 55 TO 60 EQUIVALENT PERCENT OF A POLYOL COMPONENT, UP TO 5 EQUIVALENT PERCENT OF THE POLYOL COMPONENT BEING A COMPOUND HAVING TWO HYDROXYL GROUPS, THE REMAINDER OF THE POLYOL COMPONENT BEING AT LEAST ONE COMPOUND HAVING AT LEAST THREE HYDROXYL GROUPS AND (B) A POLYESTER HAVING A SUBSTANTIALLY LOWER FUNCTIONALITY THAN THE SAID HIGHLY FUNCTIONAL POLYESTER, THE LOWER FUNCTIONALITY POLYESTER BEING DERIVED BY HEATING TO ESTERIFY A MIXTURE OF (1) FROM ABOUT 40 TO 45 EQUIVALENT PERCENT OF AT LEAST ONE DICARBOXYLIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF ISOPHTHALIC ACID AND THE 1 TO 4 CARBON ATOM DIALKYL ESTERS OF ISOPHTHALIC AND TEREPHALIC AACIDS AND (2) FROM ABOUT 55 TO 60 EQUIVALENT PERCENT OF A POLYOL COMPONENT COMPRISING (A) FROM ABOUT 20 TO 45 EQUIVALENT PERCENT OF A COMPOUND HAVING TWO HYDROXYL GROUPS AND (B) FROM ABOUT 10 TO 40 EQUIVALENT PERCENT OF AT LEAST ONE COMPOUND HAVING AT LEAST THREE HYDROXYL GROUPS, THE COMPONENTS (A) AND (B) BEING BLENDED IN PROPORTION TO PROVIDE A DIHYDROXY COMPOUND CONTENT WITHIN THE RANGE OF ABOUT 8 TO 20 EQUIVALENT PERCENT, BASED ON THE TOTAL POLYESTER BLEND OF COMPONENTS (A) AND (B).
