Structure/Property Relationships in Urethane Dimethacrylate-Based ACP Composites

In this study, the effects of two comonomers (the low molecular mass, hydrophilic 2-hydroxyethyl methacrylate (HEMA) vs. the high molecular mass, less hydrophilic, more flexible polyethyleneglycol extended UDMA (PEG-U)) on the PS, PSD and DC were assessed in UDMA/ACP composites. Additionally, dry composite specimens were evaluated for their biaxial flexure strength (BFS). Substituting PEG-U for HEMA in UDMA based ACP composites moderately improved vinyl conversion while not adversely affecting their physicochemical properties. Less polymerization stress of PEG-U formulations may result in improved clinical performance of such materials.
