  • RADIOPAQUE CATIONICALLY POLYMERIZABLE COMPOSITIONS COMPRISING A RADIOPACIFYING FILLER, AND METHOD FOR POLYMERIZING SAME
    Publication number: 20070110656
    Abstract: Polymerizable compositions that include: (a) a cationically active functional group; (b) an initiation system capable of initiating cationic polymerization of the cationically active functional group; and (c) a filler composition that includes various radiopacifying fillers in an amount sufficient to render the polymerizable composition radiopaque. Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.
