Methods for polymer synthesis
Abstract
The present invention provides methods for reducing induction periods in epoxide-CO2 copolymerizations. In certain embodiments, the methods include the step of contacting an epoxide with CO2 in the presence of two catalysts: an epoxide hydrolysis catalyst and an epoxide CO2 copolymerization catalyst. In another aspect, the invention provides catalyst compositions comprising a mixture of an epoxide hydrolysis catalyst and an epoxide CO2 copolymerization catalyst.
