Organocatalytic 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 کاملThe cationic ring-opening polymerization of tetrahydrofuran with 12-tungstophosphoric acid.
The cationic ring-opening polymerization reaction of tetrahydrofuran at 20 degrees C was catalyzed by H3PW12O40 x 13 H2O as solid acid catalyst. The effect of the proportions of acetic anhydride and catalyst, reaction time and support on the polymerization reaction was investigated. It has been found that the yield and the viscosity of the polymer depend on the proportion of acetic anhydride, t...
متن کاملGlycosylation initiated cationic ring-opening polymerization of tetrahydrofuran to prepare neo-glycopolymers.
An unprecedented and highly efficient glycosylation initiated cationic ring-opening polymerization (CROP) of tetrahydrofuran is disclosed employing glycosyl ortho-hexynylbenzoates as donors and gold(I) as a catalyst, that provides an easy access to novel glycopolymers which could self-assemble into nanostructures.
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], ...
