    摘要： Present invention provides medical material sterilized by radioisotope, comprising polymer composite using in living body, containing multifunctional triazine compounds at weight ratio range of 0.01 to 20 weight percent to the polymer. The present invention shows the fabrication of polymer composite having good heat and radiation resistance, by preventing heat molding record and irradiation on sterilized processes from deteriorating molecular weight caused on heat and radiation decomposition of the polymer. It is possible that the polymer composite is applied for the medical field of decomposable and bio-absorbable polymers and even bio-nonabsorbent polymers such as suture of operation or bonding agent for broken bone as a result. Furthermore, it is possible that the polymer composite is applied for not only medical material but also food wrapping material of industrial use.

    摘要： The present invention provides a tough denture and a method for the production thereof, which denture comprises solid PMMA as a main component, thereto being added atactic polymethylmethacrylate or polar elastomer selected from the group consisting of polyacrylate rubber co-polymer, methylmethacrylate-alkylacrylate-styrene ter-polymer, and fluoro-rubber, and which denture is fabricated in a process of being mixed and injected into a denture mold. The PMMA denture of the present invention shows improved safety to living organisms and productivity of molding because of its excellent mechanical properties and a remarkable elution volume decrease after polymerization in comparison with ordinary type dentures of heat-polymerized PMMA. Furthermore, it can be widely applied in clinical use because of its good oral adaptability and economical advantage.
