a Decision tree based on molecular weight and Tg. Within each box of the tree, value = [x, y, z] corresponds to [slow, medium, fast]. b Graphical representation of decision tree. The shaded areas reflect prediction zones that correspond to fast (yellow), medium (green), and slow (purple) degradation.
