Well-defined triblock terpolymer polystyrene-block-poly (N,N-Dimethylaminoethyl methacrylate)-block-poly (methyl methacrylate) (PS-PDMAEMA-PMMA) is synthesized via sequential Atom transfer radical polymerization (ATRP) with designed molecular weights characterized by HNMR and GPC. Annealing in Chloroform which is a selective solvent for PS and PMMA induces the formation of micelles with patchy coronas, and subsequent dialysis against cyclohexane which is selective only for PS enables the stacking of the precursor micelles into core-compartmentalized self-assemblies. The micellizatinon and self-assembly behaviors are investigated via DLS and TEM.

The polystyrene with end group of Br was synthesized by using MBrP as the initiator, CuBr/ PMDETA as the catalyst system according to atom transfer radical polymerization (ATRP). The effect of reaction temperature was studied and the system was confirmed as the active polymerization. Then PS-Br and CuBr/ PMDETA were respectively used as macroinitiator and catalyst to polymerize tBMA according to atom transfer radical polymerization (ATRP). The structure of the product was characterized by GPCFTIR1H-NMR. The amphiphilic block copolymer was obtained after hydrolysis. And the honeycomb porous film was prepared by PS-b-PMAA through using breath figure method.
