Abstract
Abstract Aromatic polyvinylethers and active hydrogen compound reaction products thereof have been found to provide fast heat curable molding compositions when used with various heat activated curing catalysts, for example, diaryliodonium salts in combination with aromatic polyvinylether soluble copper compounds, or dialkylhydroxyarylsulfonium salts in combination with certain organic oxidants.
