Abstract

A tape impregnating composition comprises (1) a polymerizable unsaturated alkyd resin e.g. diethylene glycol maleate; (2) a copolymerizable different monomer, e.g. styrene in the ratio by weight of about 1 to 3 parts of (1); (3) a catalyst for accelerating the copolymerization of the ingredients of (1) and (2), e.g. benzoyl peroxide; (4) a polyvinylacetal resin, specifically a polyvinyl formal resin, in an amount corresponding to from 15 to 75% by weight of the total of (1), (2) and (4); (5) a volatile solvent for the ingredients of (1) (2) and (4) e.g. ethylene dichloride, a mixture of ethyl alcohol and l-nitropane, a mixture of ethyl alcohol and toluene &c. and (6) an inhibitor such as quinone or hydroquinone in an amount of approximately .001% to .01% of the weight of the reactive materials of (1) and (2). Specification 531,273 is referred to.
