IMIDAZOLIUM/THIOL POLYMERIZATION INITIATION SYSTEM

Abstract:

Described herein is a new initiator system for initiating radical polymerization of ethylenically unsaturated monomers. The initiator system comprises an organic compound having N-charged moiety in combination with an organic thiol compounds. The initiator system demonstrates better stability and is suitable for use in the field of a dentistry in formulated dual cure compositions, such as a resin modified glass ionomers, a cement, an orthodontic adhesive, and composite formulations.
