HIGH MOLECULAR-WEIGHT ALIPHATIC POLYCARBONATES PREPARED USING BASE CATALYSTS

摘要

The present invention relates to a high molecular-weight aliphatic polycarbonate containing a repeating unit represented by a chemical formula 1, wherein salt comprising metal cations or onium cations and anions with the pKa value of less than 3 are dispersed. [The chemical formula 1] (Here, A is a substituted or non-substituted alkylene of C3-C60, or a substituted or non-substituted heteroalkylene of C3-C60, and each O-A-O monomer is the same or different in one polymer chain)
