季膦盐型抗菌单体及其制备方法
摘要：
本发明涉及下式的季膦盐型抗菌单体及其制备方法。该单体的一端为抗菌基团——季膦盐基团，另一端为可聚合基团——丙烯酸酯基团，中间链段为烷基链段。可聚合基团使得该单体可以通过化学反应的方式键接至牙科修复材料上，赋予其长期抗菌性能。本发明还涉及采用该季膦盐抗菌单体作为聚合单体聚合而成的聚合物材料，以及包含该聚合物材料的牙科修复材料。
摘要（英）：

The invention relates to a quaternary phosphonium salt-type antibacterial monomer shown in the formula and a preparation method thereof. One end of the monomer is an antibacterial group which is a quaternary phosphonium salt group, the other end of the monomer is a polymerizable group which is an acrylate group and the middle chain of the monomer is an alkyl chain segment. Through the polymerizable group, the monomer can be bonded to a dental restoration material through a chemical reaction so that the dental restoration material has long-term antibacterial properties. The invention also relates to a polymer prepared from the quaternary phosphonium salt-type antibacterial monomer as a polymerization monomer and also relates a dental restorative material containing the polymer.
