Cover: The figure on the left side of the cover shows a comparison of the reaction profiles in terms of molecular weight of PLA from experiments with that predicted by the model at different temperatures (110, 150, 180°C) with Ti(BuO) 4 as the catalyst. The figure on the right compares the molecular weight distribution of the polymer produced at 150°C after 48 h of reaction time as predicted by the model with that estimated through the experiment. Further details can be found in the article by Y. M. Harshe, G. Storti, M. Morbidelli, * S. Gelosa, and D. Moscatelli on page 611.
