  • Deodorizing agent for sulfur-or nitrogen-containing initiators
    Publication number: 20040242818
    Abstract: Cationic initiator compositions for initiating cationic polymerization which contain a sulfur- or nitrogen-containing initiator, such as a sulfonium salt photoinitiator, and a deodorizing agent are disclosed. The deodorizing agent reduces undesirable odors, such as the organosulfur/mercaptan/thio odor generated by the decomposition of the sulfonium salt initiator upon initiation. The deodorizing agent may be a free radical inhibitor or phenolic compound such as methylether of hydroquinone, toluhydroquinone and hydroquinone. Processes for making and using the composition are also disclosed.
