| Outline of Final Research Achievements |
The powder-liquid type poly(methyl methacrylate) (PMMA) based resin materials using the elastic paste prepared by mixing PMMA powder and monomer liquid containing of multi-functional monomer with the ability to swell PMMA powder and to form the extremely high cross-linked density network structure. The novel powder-liquid mixed type PMMA based polymer alloys with sea-island structure were developed by the polymerizing the elastic paste. As for the flexural mechanical properties, not only strength/modulus but toughness has improved, and the flexural strength was equivalent to that of commercial dental composite resin.
