Title:

METHOD FOR MANUFACTURING POLYALKYLENE CARBONATE RESIN

Document Type and Number:

WIPO Patent Application WO/2023/054999

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing a polyalkylene carbonate resin and, more specifically, to a method for manufacturing a polyalkylene carbonate resin in which, by increasing the activity of a catalyst, the content of cyclic carbonate, which is a by-product, is reduced and the ratio of repeating units containing carbon dioxide is increased.
