Aromatic polyvinyl ethers and heat curable molding compositions obtained therefrom

Claim 1

Heat curable compositions comprising, (A) aromatic polyvinylethers selected from (i) polyvinyl compounds having the formula, R[GR.sup.1 OC(R.sup.2)═C(R.sup.3).sub.2 ].sub.n, and (ii) reaction products comprising said polyvinyl compounds and from 0.1 to 1 mole, per mole of said polyvinyl compounds of an active hydrogen compound selected from polycarboxylic acids, phenols, thiols, silanes and polyols, and (B) an effective amount of a thermal curing catalyst comprising (a) an arylonium salt selected from a diaryliodonium salt and a dialkyl hydroxyarylsulfonium salt and (b) from 0.1 part of 10 parts, per part of said arylonium salt of an organic oxidant or an aromatic polyvinylether soluble copper compound, which thermal curing catalyst is capable of generating an acid having a pK value lower than 14, when the heat curable composition is heated to a temperature of at least 25° C., where G is selected from the class consisting of ##STR39## and mixtures thereof, R is a polyvalent aromatic organic radical, R 1 is a C.sub.(1-8) alkylene radical, R 2 and R 3 are the same or different monovalent radicals selected from hydrogen, halogen and C.sub.(1-8) alkyl radicals, and n is an integer equal to 2-10 inclusive.
