PROCESS FOR PRODUCING AQUEOUS DISPERSIONS OF ALIPHATIC POLYCARBONATES |
摘要 |
Processes for producing aqueous dispersions of aliphatic polycarbonates are described herein. A solution of the aliphatic polycarbonate in at least one aprotic, organic solvent comprising at least 50% by volume ethyl acetate based on the total amount of the organic solvent is provided. The aliphatic polycarbonate solution is emulsified in an aqueous emulsification medium in the presence of at least one surface-active substance to produce an aqueous emulsion of the aliphatic polycarbonate solution. The apriotic, organic solvent is removed from the emulsion by vaporization. |
