Figure 2. Conversion rate with time at the top surface and at 2-mm depth, at selected temperatures and exposure durations: (A) 40 sec, (B) 20 sec, (C) 10 sec, and (D) 5 sec, (E) natural log of Rpmax as a function of inverse temperature. A linear fit to the data was used to determine the activation energy (15.6 kJ/mol). (F) Natural log of conversion rate as a function of inverse temperature and monomer conversion at the top surface and (G) at 2-mm depth. For A–D, data at each one-second time point represent the mean of 5 replications; coefficient of variation ranged from 3.1 to 17.6%.
