Table 2 -.

Means (SD) of the viscosity (η, Pa.s) for the liquid component modified with the HDDMA and/or thiourethane, and dynamic properties of polymerized bars: glass transition temperature (Tg, °C), breadth of tan delta (width at half-height, °C) and crosslinking density (mog/kg). Different HDDMA concentrations were added to materials without (0 wt%) or with (10 wt%) thiourethane oligomer. Values followed by the same letters in each column are statistically similar (α=0.05).
