The time axis was also corrected here by 𝑡 0 . Gelation can be traced by a sudden drop in 𝑇 2 * from a nearly constant level prior to gelation. 77 Subsequently, the resulting gelation times 𝑡 𝑐 in Table were determined from the intersection of the horizontal lines with linear fits to the steepest descents of the data shown in Figure (note the logarithmic time axis). The gelation times refer to conversions at the gel point 𝑝 𝑐 according to
