  • Aliphatic polycarbonate quench method
    Patent number: 9868816
    Abstract: The present disclosure is directed to, in part, an aliphatic polycarbonate polymerization reaction initiated by combining an epoxide with carbon dioxide in the presence of a catalytic transition metal-ligand complex to form a reaction mixture, and further quenching that polymerization reaction by contacting the reaction mixture with an acid containing a non-nucleophilic anion produces a crude polymer solution with improved stability and processability.
    Type: Grant
    Filed: March 10, 2015
    Date of Patent: January 16, 2018
    Assignee: Saudi Aramco Technologies Company
    Inventors: Scott D. Allen, Jeffrey R. Conuel, David E. Decker, Anna E. Cherian

  • Tunable polymer compositions
    Patent number: 8575245
    Abstract: The present invention provides polycarbonate compositions having a tunable decomposition temperature. Suitable cationic additives (e.g., phosphonium, phosphazene, quaternary ammonium, guanidinium, pyridinium, arsonium, etc.) are disclosed for lowering the decomposition temperature of polymer compositions. The invention further provides methods of preparing such polymer compositions with tunable decomposition temperatures.
