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. |
