Near infrared analysis and dynamic mechanical analysis were used to characterize DC and viscoelastic properties of sixteen PICN: one control (thermo-cured) and fifteen experimental groups (one thermo-cured followed by PC and fourteen high pressure polymerized PICN, in the range of 50–350 MPa without and with PC). Conversion degree of high pressure polymerized PICN blocks without post curing displays an optimum between 100 and 150 MPa resulting in an improved E′ and Tg. Post curing induces a higher DC with a controversial effect on thermomechanical properties. The results suggested that 100–150 MPa without PC is an optimum polymerization parameter, resulting in PICN blocks with significantly better DC, Tg, E’.Show less >
