Abstract
The addition of a small amount of a second epoxide to the copolymerization of ethylene oxide or propylene oxide with carbon dioxide can give a melt processable polyalkylene carbonate terpolymer which can be processed without extensive thermal decomposition. This invention has particular utility in thermoplastic applications such as injection molding, blow molding, and film manufacture.
