Polycondensation in batch is the classical way to produce polyesters. However, this method requires harsh conditions reach high conversions and drive equilibrium of reaction forward. In order controlled polymers a greener way, we worked on enzymatic ring opening polymerization (e-ROP) lactones using CALB lipase immobilized porous beads (Novozym® 435) as catalyst 3-phenyl-1-propanol (PP) initiat...

N -carboxyanhydrides ring-opening polymerization (ROP) showed that electron-donating groups of the -alkylation enhanced ROP kinetic rates through an inductive effect could counterbalance steric hindrance during propagation.
