The present invention provides a dental polymerizable composition that requires less discharging force, is easily formable, has low polymerization shrinkage stress during curing, and exhibits high stain resistance and surface gloss when cured. The present invention relates to a dental polymerizable composition including a (meth)acrylic block copolymer (A), a polymerizable monomer (B), and a polymerization initiator (C). The (meth)acrylic block copolymer (A) consists of a (meth)acrylic polymer block (a) having a curable functional group and a (meth)acrylic polymer block (b) having no curable functional group. The curable functional group has a partial structure represented by the following general formula (1):
本发明提供了一种牙科可聚合组合物,该组合物所需的放电力较小,易于成型,固化过程中的聚合收缩应力较低,固化后具有较高的抗污性和表面光泽。本发明涉及一种牙科可聚合组合物,包括(甲基)丙烯酸嵌段共聚物(A)、可聚合单体(B)和聚合引发剂(C)。甲基丙烯酸嵌段共聚物(A)由具有可固化官能团的甲基丙烯酸聚合物嵌段(a)和不具有可固化官能团的甲基丙烯酸聚合物嵌段(b)组成。可固化官能团的部分结构由以下通式(1)表示:
