Abstract

Azide end-functionalized polyhedral oligomeric silsesquioxane (POSS-N ₃) was incorporated into the periphery of well-defined alkyne-polystyrene₅₀-poly(divinyl benzene) (alkyne-PS ₅₀-polyDVB) and alkyne-poly(tert-butyl acrylate)₄₃- poly(divinyl benzene) (alkyne-PtBA₄₃-polyDVB) multiarm star polymers via highly efficient azide-alkyne click reaction, resulting in POSS-PS ₅₀-polyDVB and POSS-PtBA₄₃-polyDVB multiarm star block copolymers respectively, in the solution of tetrahydrofuran/N,N-dimethyl formamide, CuBr/N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA) at room temperature for 24 h. Linear precursors and star polymers obtained in this study were characterized ¹H NMR, gel permeation chromatography (GPC), and triple detection GPC (TD-GPC). Absolute molecular weight, hydrodynamic radius, and intrinsic viscosity ([η]) values for all star polymers were determined by TD-GPC.
