Abstract

We present a combinatorial approach to the synthesis of block copolymer series by anionic polymerization, utilizing a specially designed reactor setup. The setup features one main reactor and three secondary reactors to carry out anionic polymerizations on laboratory-scale quantities at low temperatures. The implementation was demonstrated with three series of AB- and ABC-block copolymers with identical A- and AB-blocks, respectively. The B-block in AB-diblock copolymers and the C-block in ABC-triblock copolymers can be varied with respect to block length or chemical constitution. Well-defined series of block copolymers are useful for advanced optimization of functional block copolymers in nanotechnology applications.
