Aliphatic polyesters have received considerable attention in recent years due to their biodegradability and biocompatible, mechanical, thermal properties that can make them a suitable alternative today's commercialized polymers. The ring-opening copolymerization (ROCOP) of epoxides cyclic anhydrides is route synthesize diverse array could be useful many applications. However, the catalysts used rarely consider biocompatible case any are left polymer. To best our knowledge, we report first...
Monometallic yttrium β-diketiminate complexes are active and controlled catalysts for perfectly alternating ring-opening copolymerization of 1-butene oxide phthalic anhydride under mild conditions. β-Diketiminate ligands with pendant neutral donors were targeted to identify both the impact donor strength number on rates polymerization presence undesirable side reactions. Initiating groups also varied between alkyls, chlorides, alkoxides. In a cocatalyst, studied minimal reactions, whereas...
Abstract The perfectly alternating ring‐opening copolymerization of epoxides and cyclic anhydrides has been an emerging route to diverse polyesters. Simple catalysts have targeted for this polymerization decrease the cost air‐sensitivity catalysis. This report improves upon recently reported YCl 3 ⋅ 6H 2 O/[PPN]Cl (bis(triphenylphosphine)iminium chloride) binary catalyst system, which shows fast rates but suffers from low molecular weights due presence many water chain transfer agents. In...
Ligand features that promote one-pot block copolymerization of 1,3-dienes and cyclic esters were realized with yttrium β-diketiminate complexes. Depolymerization repolymerization the polyester introduced a plausible recycling strategy.
