Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.
描述了一种在牙科修复、薄膜、硬涂层、复合材料、粘合剂等需要减压的用途中应用的新型减压交联寡聚体。交联的加成-断裂过程导致链转移事件,提供了可以进一步功能化的新型聚合物。此外,加成-断裂寡聚体包括侧链功能基团,通过形成离子键或共价键与基底结合,或通过化学去除基底上的部分材料来蚀刻基底。
