THERMALLY PORIMERIZABLE COMPOSITION CONSISTING OF EPOXIDE RESIN, AROMATIC SULFOXONIUM SALT AND ORGANIC OXIDIZING AGENT AND POLYMERIZATION

Certain classes of aromatic sulfoxonium salts, such as dimethylphenacylsulfoxonium and acetanilinodimethylsulfoxonium hexafluorophosphates, have little or no effect on prolonged heating with O-glycidyl group-containing epoxides. It has now been found that if a quinone, peroxide, or iodoso aromatic c...

Zusammenfassung:	Certain classes of aromatic sulfoxonium salts, such as dimethylphenacylsulfoxonium and acetanilinodimethylsulfoxonium hexafluorophosphates, have little or no effect on prolonged heating with O-glycidyl group-containing epoxides. It has now been found that if a quinone, peroxide, or iodoso aromatic compound is also added, the sulfoxonium salts rapidly bring about the polymerization of such epoxides and curing of such polyepoxides.
