Synthesis of polystyrene-b-polyurethane-b-polystyrene copolymers through ARGET ATRP polymerization method. Part II. Chemical structure, thermal and surface properties

摘要

The chemical structures of the synthesized previously [1] bromourethane macroinitiator (MBP-PUR-MBP) and urethane-styrene copolymer were determined using FT-IR. H-1 and C-13 NMR spectral methods and confirmed by the results of thermal analysis (DSC and TGA). The studies of surface properties (roughness, contact angle and SFE) of polymer films prepared from these copolymers indicate, by an increase in hydrophobicity, the presence of block segments derived from PS.
