Abstract

The present invention relates to an organic solvent-soluble copolymerized polyester, a composition for forming an ultrafiltration membrane including the same, and a high water-permeability reverse osmosis membrane prepared therefrom. More specifically, the present invention relates to a polyester that has a high solubility in organic solvents at room temperature and thus can be used to produce ultrafiltration membranes at low cost, a composition for forming an ultrafiltration membrane including the same, and a high water-permeability reverse osmosis membrane prepared therefrom, wherein the reverse osmosis membrane has a reduced production cost and high water permeability.
