Synthetic copolymer resinous insulating compositions

Claim 1

AN INSULATED ELECTRICAL MEMBER COMPRISING AN ELECTRICAL CONDUCTOR, A RELATIVELY THICK LAYER OF A CURED SOLID RESINOUS COPOLYMER APPLIED TO THE EXTERIOR SURFACE OF SAID MEMBER TO PROVIDE AN OUTER ENCAPSULATING SHELL THEREFOR, AND A CURED SOLID RESINOUS COPOLYMER DISPOSED WITHIN AND COMPLETELY FILLING THE ENCAPSLATING SHELL AND IMPREGNATING THE INTERSTICES OF SAID MEMBER, THE CURED SOLID RESINOUS COPOLYMER COMPRISING A COMPLETELY REACTIVE SYNTHETIC COPOLYMERIZABLE RESINOUS COMPOSITION COMPRISING (A) FROM 5% TO 95% BY WEIGHT OF A PRODUCT OBTAINED BY ADMIXING (A) THE ESTER REACTION PRODUCT OF A RESINOUS POLYMERIC EPOXIDE AND AT LEAST ONE HIGHER FATTY ACID WITH (B) THE ACID HALF-ESTER OBTAINED UPON REACTING AT LEAST ONE POLYHYDRIC ALCOHOL ESTER OF A HYDROXYLATED UNSATURATED FATTY ACID WITH AT LEAST ONE ALPHA-BETA ETHYLENICALLY UNSATURATED DICARBOXYLIC ACID AND ANHYDRIDES THEREOF, THE MATERIALS BEING PRESENT IN AMOUNTS SUCH THAT THERE ARE AS MANY EPOXIDE GROUPS ON THE RESINOUS POLYMERIC EPOXIDE AS THE TOTAL NUMBER OF CARBOXYL GROUPS SUPPLIED BY THE SAID HIGHER FATTY ACIDS AND THE SAID REACTION PRODUCT OF THE FATTY ACID ESTER AND THE ALPHA-BETA ETHYLENICALLY UNSATURATED DICARBOXYLIC ACIDS, AND (B) FROM 95% TO 5% BY WEIGHT OF A LIQUID UNSATURATED REACTIVE MONOMER OF A VINYL COMPOUND HAVING THE GROUP
