| Abstract/Summary |
The focus of this work was to synthesize and characterize poly(propylene carbonate) made from CO2 and propylene oxide. Reactions were conducted in a high-pressure Parr reactor using
a double metal cyanide catalyst and a poly(propylene glycol) initiator. The polymers were analyzed using GPC and 1H NMR. It was found that increasing the mol % of initiator in the reaction
decreased molecular weight without affecting carbonate percentage. It was also determined that the increase of CO2 pressure in the reaction increased the amount of carbonate units in the polymer,
without affecting molecular weight.
