DESCRIPTION (provided by applicant): The proposed research is to develop thiol-ene polymers for application as dental restorative materials. The goals of this research are to develop thiol-ene materials that will have superior properties relative to current polymers utilized for dental restorative materials. The research will involve studying the relationship between chemical structure, polymerization kinetics, and material properties, these studies will be conducted with commercially available monomers and also novel thiol and ene monomers synthesized in the Bowman and Stansbury research groups. Thiol-ene based dental composite systems with filler particles will also be studied. Critical areas that will be addressed are volume shrinkage and shrinkage stress as well as the stability of the monomer formulations. The compatibility of monomer formulations with filler particles and the properties of filled systems will be evaluated. Biocompatibility of the new dental restorative materials will also be assessed.

描述（由申请人提供）：拟议的研究是开发硫醇 - 烯聚合物作为牙科修复材料的应用。这项研究的目标是开发相对于用于牙科修复材料的当前聚合物具有较高特性的硫醇材料。该研究将涉及研究化学结构，聚合动力学和材料特性之间的关系，这些研究将与 在鲍曼和斯坦斯伯里研究小组中合成的市售单体以及新颖的硫醇和ENE单体。还将研究带有填充颗粒的硫醇基牙科复合系统。将要解决的关键领域是体积收缩和收缩应力以及单体配方的稳定性。将评估单体配方与填充颗粒的兼容性以及填充系统的性能。新牙科修复材料的生物相容性也将被评估。
