a
C0 was mixture of HEMA and BisGMA with a weight ratio of 45/55 (w/w).
b
The weight percent of coinitiator to the total resin.
c
The degree of conversion was obtained by real-time FTIR method after irradiation 600 s.
d
P.R.= Rp/[M0], s−1.
e
The appearance of polymer beams observed after the LED light 40-s irradiation. The value in the () is the standard deviation. – indicated the value cannot be obtained due to the characteristic peak of epoxy was too small.
