Table 2.

FTIR, tensometery, and linometery were used to measure functional group conversion, final polymerization shrinkage stress, and dynamic volumetric shrinkage, respectively. Bulk photo-CuAAC polymers denoted as BZ-AZ and BPA-AZ and a dimethacrylate-based control denoted as BisGMA/TEGDMA were compared. Each mixture was irradiated for 90 s at ambient temperature with 500mW cm⁻² of 400-500nm light. The only exception was made for BPA-AZ which was irradiated for 60 s in the volumetric shrinkage measurements. Conversion from shrinkage stress measurement is presented with conversion from volumetric shrinkage measurement being in parentheses. Within each row, the letters indicate statistically significant differences (p<0.05) via a one-way ANOVA and a Tukey's test.

Conversion [%]	75±4^B (77±3)^C	98±0.4^A (98±1)^A	83±4^B (87±0.2)^B
Shrinkage stress [MPa]	1.3±0.08^A	0.43±0.07^B	0.27±0.03^C
Dynamic volumetric shrinkage [%]	7±0.08^A	6.2±0.3^B	6.4±0.6^A,B
Shrinkage [ml/functionality]	20±1^A	22±1^A	21±2^A
