Copolymerization of CO2 and 1,2-Cyclohexene Oxide Using a CO2-Soluble Chromium Porphyrin Catalyst
Abstract
The copolymerization of 1,2-cyclohexene oxide (CHO) with carbon dioxide was performed, using supercritical carbon dioxide (scCO 2 ) as both solvent and reactant, to produce an aliphatic polycarbonate. A CO 2 -soluble catalyst, tetra(pentafluorophenyl)porphyrin chromium(III) chloride (CrTFPPCl), was synthesized and used to catalyze the polymerization in the presence of 4-(dimethylamino)pyridine (DMAP) as cocatalyst. The best yields for the copolymerization (up to ∼75%) were obtained in the temperature range 95−110 °C over a period of 18 h, with a molar ratio of catalyst to monomer of 2.6 × 10 -3 . High catalyst efficiencies (3.9 kg of polymer/g of Cr) were observed under these conditions. The copolymers consisted predominantly of carbonate linkages (90−97%), and the chain microstructure was analyzed by 1 H NMR and 13 C NMR spectroscopy. Gel permeation chromatography revealed number-average molecular weights ( M n ) of the order of 3500. In contrast to previous studies involving supercritical CO 2, narrow polymer molecular weight distributions were observed throughout ( M w / M n < 1.4).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
