Synthesis, molecular characterization and self-assembly of (PS-b-PDMS)n type linear (n = 1, 2) and star (n = 3, 4) block copolymers

Abstract

Well-defined linear (n = 1, 2) and star (n = 3, 4) architecture [polystyrene-b-poly(dimethylsiloxane)]n or (PS-b-PDMS)n block copolymers were synthesized by anionic polymerization and using various chlorosilanes as linking agents. The self-assembly of the novel synthesized copolymers revealed that microphase separation for the star-block copolymers is significantly influenced by entropy constraints due to the increased number of junction points.
