Abstract
In attempt to improve the physical properties of dental resinous materials, tris (2-methacryloxyethyl) isocyanurate (TMEIC) was synthesized from tris (2-hydroxyethyl) isocyanurate and methacryloyl chloride. The relationship between the chemical structure of the synthesized methacrylate and physical properties of TMEIC-MMA copolymers and trimethylol propane trimethacrylate (TMPT)-MMA copolymers were investigated, and we found the following; 1) The compressive strength, elastic modulus and Knoop hardness were increased, but transverse strength decreased with an increase in the TMEIC concentration. 2) The amount of water sorption increased with an increase in the TMEIC concentration. 3) The physical properties of TMEIC-MMA copolymers were relatively higher than those of TMPT-MMA copolymers.
