Photopolymerizable compositions that include free radically active and cationically active functional groups, and methods for polymerizing such compositions, in which the onset of cationic polymerization is controllably delayed to extend the time between formation of a moldable gel and formation of a hardened solid.
L'invention concerne des compositions dentaires photopolymérisables incluant un groupe fonctionnel actif à radicaux libres et un groupe fonctionnel actif cationique. L'invention concerne également des procédés de polymérisation desdites compositions dans lesquels le début de la polymérisation cationique est retardé de manière régulée pour prolonger le laps de temps entre la formation d'un gel moulable et la formation d'un solide durci.
