Density measurements, mechanical properties, and crosslinking characterization of photocrosslinked and ester bond crosslinked POMaC networks. EPOMaCs were post-polymerized at 80 °C for the corresponding number of days in parenthesis. EPPOMaC polymers were crosslinked under UV irradiation for 10 min, 30% polymer concentration, 1 (wt%) PI, and post-polymerized at 80 °C for the corresponding number of days in parenthesisa
