Dendrimers/Hyperbranched/Star Polymers

摘要

Two diblock copolymers respectively, poly(styrene-b-vinyl phenol) and poly(methyl methacrylate-b-vinyl pyridine) were synthesised by anionic polymerisation. The mixing of the two polymers in THF yielded assemblies of vesicles driven by the strong hydrogen bonding between complementary binding sites on poly(styrene-b-vinyl phenol) and poly(methyl methacrylate-b-vinyl pyridine) blocks. When blended in DMF, the weaker hydrogen bonding resulted in formation of spherical micelles having compartmentalised coronas consisting of poly(styrene) and poly(methyl methacrylate) blocks.
