HYDROLYSIS TRANSFORMATION OF A POLYSTYRENE—b—POLY（tert—BUTYL ACRYLATE） COPOLYMER AND MICELLIZATION PROPERTIES OF THE HYDROLYZED COPOLYMER

摘要

A very mild and extremely efficient hydrolysis method for transformation of polystyrene-b-poly(tert-butyl acrylate)(PS-b-PtBA)to polystyrene-b-poly(acrylic acid)(PS-b-PAA) was designed and carried out using more convenient and inexpensive chlorotrimethylsilane/sodium iodide as reagents.The hydrolysis product can self-assemble in aqueous media to give regular micelles with PS block forming the core and PAA block forming the corona,or in tetrahydrofuran (THF) to give reverse micelles with the hydrophilic block in the core.
