Separation method of organic zinc catalyst using filtration membrane |
| abstract |
The present invention relates to a method for separating an organic zinc catalyst dispersed in a solution by filtering a polyalkylene carbonate resin solution. When the organic zinc catalyst separation method according to the present invention is used, the organic zinc catalyst particles are efficiently removed from the polyalkylene carbonate resin solution to obtain a transparent, high-purity polyalkylene carbonate solution. |
