DOPE COMPOSITION FOR FORMING HOLLOW FIBER MEMBRANE HAVING IMPROVED STRENGTH AND WATER PERMEABILITY AND PREPARATION METHOD FOR HOLLOW FIBER USING THE SAME

摘要

The present invention provides a composition for spinning a hollow fiber membrane. The composition for spinning a hollow fiber membrane comprises a matrix resin, a bridge forming resin, a pore former, and a nonsolvent. The weight-average molecular weight of the pore former is 800 or lower. Accordingly, a hollow fiber membrane exhibiting excellent strength and water permeability can be manufactured.
