The ring-opening polymerization (ROP) kinetics of e-caprolactone and lactide with various H-bonding organocatalysts, (thio)ureas paired with an amine cocatalyst, were evaluated at temperatures up to 110 °C. In nonpolar solvent, most cocatalyst syste

The developing urea class of H-bond donors facilitates the solvent-free ROP of lactones at ambient and elevated temperatures, displaying enhanced rates and control versus other known organocatalysts for ROP under solvent-free conditions. The ROPs ret

A new class of H-bond donating ureas was developed for the ring-opening polymerization (ROP) of lactone monomers, and they exhibit dramatic rate acceleration versus previous H-bond mediated polymerization catalysts. The most active of these new catal

Bimolecular, H-bond mediated catalysts for ring-opening polymerization (ROP)—thiourea or urea plus base, squaramides and protic acid/base pairs, among others—are unified in a conceptual approach of applying a mild Lewis acid plus mild Lewis base
