A parametric study of the terminal maleation of polypropylene through an Alder Ene reaction

A study of the parameters that affect the Alder Ene reaction with respect to the synthesis of a terminally anhydride‐functionalized polypropylene was carried out over a temperature range of 220–250°C using maleic anhydride concentrations of 2–12 mol equivalence with respect to the vinylidene group. As previously observed, a Lewis acid (i.e., SnCl2 · 2H2O) had a catalytic effect on the reaction at these temperatures, thereby improving anhydride …
