Lipase-catalyzed Continuous Ring-opening Polymerization ofe-Caprolactone in a Packed-bed Reactor
A packed-bed reactor (PBR) system was developed for continuous lipase-catalyzed ring-opening polymerization of -caprolactone ( -CL). The parameters affecting the poly( -caprolactone) (PCL) production in the PBR such as residence time, height to diameter (H/D) ratio, and monomer feed concentration were investigated. Monomer conversion of -CL increased with the increase of residence time, reached...
متن کاملZinc-Catalyzed Highly Isoselective Ring Opening Polymerization of rac-Lactide
A family of chiral zinc amido-oxazolinate complexes are shown to be highly active and isoselective initiators for the ring-opening polymerization (ROP) of rac-lactide, yielding isotactic stereoblock polylactides (PLA) with Pm up to 0.91. This represents the highest isoselectivity observed with zinc-based catalysts for ROP of rac-lactide.
متن کاملOrganocatalytic ring-opening polymerization.
Modern synthetic methods have revolutionized polymer chemistry through the development of new and powerful strategies for the controlled synthesis of complex polymer architectures.1-5 Many of these developments were spawned by new classes of transition metal catalysts for the synthesis of new polyolefin microstructures,5 the design of highly efficient families of “living” polymerization strateg...
متن کاملThermodynamics and Kinetics of Ring - Opening Polymerization
Cyclic monomers that have been polymerized via ring opening encompass a variety of structures, such as alkanes, alkenes, compounds containing heteroatoms in the ring: oxygen [ethers, acetals, esters (lactones, lactides, and carbonates), and anhydrides], sulfur (polysulfur, sulfi des and polysulfi des), nitrogen [amines, amides (lactames), imides, N carboxyanhydrides and 1,3 oxaza derivatives], ...
