a
ΔH is the measured heat of polymerization; tmax is the time to maximum of polymerization rate; t95% is the time to 95% of heat evolution.
b
G′final is the final storage modulus; tgel is the time to gel point; DBCgel is the double-bond conversion at gel point; DBCfinal is the final double-bond conversion; FN is the measured normal force. Standard deviation for final values can be seen in Tables S1 and S2.
c
The initial measurement period of 5 s before light irradiation has been subtracted.
