Room temperature cationic polymerization of β-pinene using modified AlCl3 catalyst: toward sustainable plastics from renewable biomass resources

The polymerization of β-pinene is efficiently prompted by AlCl3 etherates to afford relatively high molecular weight polymers (Mn = 9000–14 000 g mol−1) with good thermal properties (Tg = 82–87 °C) at room temperature and low catalyst content (2.5–5.5 mM).
