Abstract

PURPOSE: An ethylenically unsaturated carboxylic acid and a polyamine are added to a prepolymer with the main chain of polyether bearing isocyanate groups on the chain terminals in specific proportions and they are cured by heating, thus producing title composition with good failure characteristics and dissipation factor.
CONSTITUTION: To (A) 100 parts by wt of prepolymer with the polyether main chain bearing terminal isocyanate groups, preferably of 2,000W5.000 molecular weight, are added (B) 5W40 parts of (a) an α, β-ethylenically unsaturated carboxylic acid or (b) a mixture consisting of more than 10wt% of (a) and a vinyl monomer compatible to component (a) as methyl methacrylate, (c) 0.05W3 parts of an organic peroxide as t-butylperoxy benzoate and (D) 0.5W1.1 equivalent, as the equivalency of active hydrogens per one equivalent of NCO, of a polyamine as 4, 4'-methylene-bis-o-chloroaniline and the mixture is cured by heating at 40W 140°C to produce the objective composition.
