Abstract

A capacitor section with terminals exposed at the ends of an encompassing tubular pre-fabricated casing is impregnated with a mixture of an unsaturated alkyd resin having an acid number below 20 and a compatible liquid monomer such as styrene, the mixture then being copolymerized, suitably at a temperature of 150 DEG F. As an unsaturated alkyd resin there is specified one derived from maleic anhydride and ethylene glycol as principal constituents, as described in Example 4 of Specification 679,539. The polymerization step may be conducted in the presence of catalysts and inhibitors.
