摘要
The present invention relates to a polymer additive for preparing a microfiltration membrane or an ultrafiltration membrane that contains a polysulfone-based polymer which has a specific chemical structure, and a method for preparing the same. According to the polymer additive, pores can be efficiently formed on a surface of a filtration membrane, and thus the shape and size of the pores can be adjusted with ease. In addition, the water permeability of the filtration membrane can be improved while a fouling phenomenon, in which contaminants are adsorbed to the surface of the filtration membrane, can be significantly reduced due to insolubility even after a long period of use.
