An alternative analysis was proposed by Patrone, 71 in which the empirical tangents to the low-and high-temperature branches are replaced by analytic tangents of the hyperbola fitted to the entire data set. Since the fit is unique, the ambiguity is removed (see Figure ). In the ideal case when the asymptotic behavior is well captured by the simulations, both procedures should give identical T g . However, since the transition point shifts with the curing intensity, the asymptotic behavior may not have been achieved in the window of realistic temperatures. For example, data for small curing have a very short region in the liquid state, and obtaining asymptotic behavior there is not possible. One further limitation of both methods is that the density data sets are not showing a hyperbolic trend at temperatures away from T g . Thus, addressing these data sets using hyperbolas that rely on the extremities of the studied temperature window may lead to wrong estimation of the glass transition (Figure ).
