| Research Abstract |
The urethane dimethacrylate(UDMA)/methacrylic acid(MAA) resin with the characteristic high cross-linked network structure consist of covalent and hydrogen bonds was improved the mechanical properties(MP) than the conventional dental matrix resins. And the polymerized elastic pastes of multi-functional aliphatic vinyl esters(MFVE) and poly methyl methacrylate(PMMA) were also improved the MP than the commercial acrylic denture base resin. Moreover, the saturated water uptake of vinyl methacrylate(VMA)/PMMA resin was low than that of expectation based on the hydrophilic-lipophilic balance of VMA, and was significantly low than that of MMA/PMMA resin. The characteristic properties of VMA/PMMA resin were anticipated based on the extremely high density cross-linked network structure of poly-VMA.
