Abstract
Initiator systems of the invention comprise a complexed initiator comprising a complex of an amidine complexing agent and an initiator; and a decomplexer. The initiator systems are useful for initiating polymerization of at least one monomer to form polymerized compositions. Kits of the invention useful for forming the polymerized compositions comprise a polymerizable composition and an initiator component, wherein the initiator component comprises a complexed amidine initiator. Bonding compositions can be prepared by mixing the polymerizable composition of the kit with the respective initiator component.
