The present invention provides a polymerizable monomer represented by the following general formula (1) useful as a dental material. In the general formula (1), Ra is a divalent aromatic hydrocarbon group having 6 to 9 carbon atoms or a cyclic hydrocarbon group which may have a divalent bridge structure having 6 to 9 carbon atoms. , R1 and R2 are hydrogen atoms or alkyl groups having 1 to 3 carbon atoms, R3, R4, R5 and R6 are hydrogen atoms or hydrocarbon groups, R7 and R8 are hydrogen atoms or methyl groups, m and n is each independently 0 to 4; Rb and Rc are each independently a hydrogen atom in which a hydrogen atom may be substituted with an alkyl group having 1 to 3 carbon atoms or a (meth) acryloyloxymethylene group; -6 linear alkylene group or a C2-C6 linear oxyalkylene group is shown.本発明は、歯科材料として有用な下記一般式(1)で表される重合性モノマーを提供する。 上記一般式(1)中、Raは二価の炭素数6~9の芳香族炭化水素基又は二価の炭素数6~9の橋かけ構造を有してもよい環式炭化水素基であり、R1及びR2は水素原子又は炭素数1~3のアルキル基であり、R3、R4、R5及びR6は水素原子又は炭化水素基であり、R7及びR8は水素原子又はメチル基であり、m及びnはそれぞれ独立に0~4であり、Rb及びRcは、それぞれ独立に、水素原子が炭素数1~3のアルキル基又は(メタ)アクリロイルオキシメチレン基で置換されていてもよい、炭素数2~6の直鎖アルキレン基又は炭素数2~6の直鎖オキシアルキレン基を示す。
