| Popis: | Terpolymers with various l-lactic acid content in the polypropylene carbonate chain were synthesized by copolymerization of carbon dioxide, propylene oxide, and l-lactide. Zinc adipate was used as a catalyst. Terpolymerization products were characterized by 1H and 13C NMR, 2D {1Н—13С} HMBC, IR spectroscopy, and gel-permeation chromatography. The influence of monomer molar ratio, temperature, and reaction duration on the composition and molecular-mass characteristics of terpolymers was studied. A few questions of terpolymerization mechanism were discussed. |
