Abstract
A novel, facile method to prepare copolymers by virtue of the reinitiation of precursor containing isopropylthioxanthone (ITX) residues (ITXH) was reported. Using poly(maleic anhydride-co-vinyl acetate) (P(MAH-co-VAc)) with incorporated ITX residues as a macroinitiator, polymerization of styrene was performed, and poly(maleic anhydride-co-vinyl acetate)-b-polystyrene (P(MAH-co-VAc)-b-PSt) was produced. Applying the resultant copolymer in a breath figure procedure, honeycomb structure films having pore size around 250 nm were prepared under low temperature and relative humidity.
