Adamantane derivatives in which two (meth)acryloyloxyalkyl groups are bonded with an adamantane ring through ester groups, adamantane derivatives in which two adamantane rings are bonded through an alkylene group and two urethane bonds, which two adamantane rings each have a (meth)acryloyloxy group bonded thereto directly or through a coupling group, and adamantane derivatives each having a structure in which a group containing an adamantane ring hangs on the alkylene group of an alkylene glycol di(meth)acrylate. The compounds are useful as dental materials intermediates therefor, and as intermediates for optical materials such as lenses.
含有两个(甲基)丙烯酰氧基烷基基团通过酯基与金刚烷环结合的金刚烷衍生物,含有两个金刚烷环通过烷基基团和两个脲醚键结合的金刚烷衍生物,其中每个金刚烷环各有一个(甲基)丙烯酰氧基团直接或通过偶联基与之结合,以及含有含有金刚烷环的基团悬挂在烷基二(甲基)丙烯酸酯的烷基基团上的结构的金刚烷衍生物。这些化合物可用作牙科材料及其中间体,以及用于光学材料如透镜的中间体。
