| Research Abstract |
In this project, amphiphilic block- and graft-polymer were prepared by using poly(trimethylene carbonate) (PTMC) as an amorphous polymer. The polymers spontaneous formed polymer colloid in water, which involved hydrophobic domain with low polarity. Asymmetrical porous membrane was prepared by blending cellulose acetate with the resulting amphiphilic polymer. The membrane was evaluated in terms of solute permeability, and 10,000 Da of molecular weight cut off was achieved. The fundamental mechanism would be surface enrichment of amphiphilic polymer on the skin layer of the porous membrane.
