Abstract
The organocatalyzed ROP of some 4-alkoxymethylene-β-propiolactones (BPL<sup>OR</sup>s) towards the formation of the corresponding poly(hydroxyalkanoate)s (PHAs; PBPL<sup>OR</sup>s) is investigated simply using basic organocatalysts of the guanidine (TBD), amidine (DBU) or phosphazene (BEMP) type.
