摘要:硫醚-烯光聚合在学术研究中越来越受到关注.由于其独特特性,硫醚-烯光聚合在涂层和牙科修复方面具有有趣的应用.在大多数研究中,相对柔韧和亲水性的酯衍生物,即对羟基丙酸四羟基戊酸四酯(petmp),被作为硫醚组分进行研究.因此,在本研究中,我们鼓励研究更具疏水性的无酯硫改性双酚和三酚衍生物在硫醚-烯光聚合中的性能.为此,通过将硫乙酸加成到适当的烯丙基改性前体中,并随后水解,合成了具有四至六个硫基团的六种不同硫改性双酚和三酚衍生物.与petmp相比,在使用1,3,5-三烯基-1,3,5-三嗪-2,4,6-三酮(tatato)作为烯基衍生物的硫醚-烯光聚合中,可以获得更好的抗弯强度和弹性模量.特别是,在水中存储后,抗弯强度和弹性模量比petmp参考系统高出一倍.
