<P>Interfacial polymerization of an acid chloride-containing block polymer and a multivalent amine in the presence of a macroporous support was explored as a means to generate a nanoporous thin film composite (TFC) membrane potentially useful for ultrafiltration. When polylactide-<I>b</I>-poly(styrene-<I>co</I>-vinylbenzoyl chloride) (PLA-<I>b</I>-P(S-<I>co</I>-VBC)) in an organic phase and <I>m</I>-phenylenediamine (MPD) in an aqueous phase were used as the reactive block polymer and the amine, respectively, a block polymer thin film was successfully formed on a polysulfone support. This nanostructured film could be converted into a nanoporous layer by subsequent PLA etching under mild basic conditions. While most organic solvents used to dissolve PLA-<I>b</I>-P(S-<I>co</I>-VBC) damaged the support and decreased permeability of the resulting membrane, use of a mixture of methyl isobutyl ketone and acetonitrile produced a TFC membrane with high permeability.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/iecred/2014/iecred.2014.53.issue-48/ie5032259/production/images/medium/ie-2014-032259_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ie5032259'>ACS Electronic Supporting Info</A></P>
