The sequential ring-opening polymerizations (ROP) of ε-caprolactone (ε-CL) and L-lactide (LLA) with benzo-12-crown-4-imidazole carbene (B-12-C-4imY) as the catalyst have been performed. Using either benzyl alcohol or ethylene glycol as an initiator, the corresponding poly(ε-caprolactone)-poly(L-lactide) (PCL-b-PLLA) diblock or poly(L-lactide)-poly(ε-caprolactone)-poly(L-lactide) (PLLA-PCL-PLLA) triblock...
An organocatalytic approach to ring-opening polymerization using N-heterocyclic carbene as nucleophilic catalyst is detailed. The influences of monomer/initiator molar ratio ([M]/[I]), monomer/catalyst molar ratio ([M]/[C]), monomer concentration, as well as polymerization temperature and time on the polymerization have been investigated. The detailed kinetic study of L-lactide (LLA) polymerization...
