Abstract
The present invention provides polymerizable monomers represented by the following general formula (1) that are useful as dental materials.In the general formula (1), Ra is a divalent C6-9 aromatic hydrocarbon group or a divalent C6-9 optionally bridged cyclic hydrocarbon group, R1 and R2 are each a hydrogen atom or a C1-3 alkyl group, R3, R4, R5 and R6 are each a hydrogen atom or a hydrocarbon group, R7 and R8 are each a hydrogen atom or a methyl group, m and n are each independently 0 to 4, and Rb and Rc are each independently a C2-6 linear alkylene or C2-6 linear oxyalkylene group optionally substituted with a C1-3 alkyl group or a (meth)acryloyloxymethylene group in place of a hydrogen atom.
