ABSTRACT:
Curable organic resin compositions, such as epoxy resins, are provided, based on the use of dialkyl hydroxy arylsulfonium salts in combination with certain orgainc oxidants such as iodosoaromatic esters, or the use of certain amines or transition metals in combination with organic peroxides. The curable compositions can provide flexible or rigid organic resin foam when used with a volatile organic solvent as a result of exothermic heat of cure.
