Process for preparing modified poly(alkylene carbonate) polyahls |
| abstract |
The invention is a process for modifying and increasing the molecular weight of a poly(alkylene carbonate) polyahl, which comprises contacting the poly(alkylene carbonate) polyahl, with at least one modifier having a plurality of moieties that are reactive with the carbonate and/or acting hydrogen moieties of the poly(alkylene carbonate) polyahl at elevated temperatures and at a pressure at which at least one compound other than a monoalkylene glycol which compound is at least as volatile as a tetraethylene glycol is removed in the gaseous state from the poly(alkylene carbonate) polyahl. |
