Abstract
Abstract Heat curable compositions are provided comprising cationically polymerizable organic materials such as epoxy resins, vinyl ethers or phenol formaldehyde resins and thermal curing agents, based on the use of certain aryl sulfonium salts with an organic oxidant, such as an organic peroxide, azonitriles, etc. The heat curable compositions can be used as injection molding compounds or as a coating composition.
