Abstract

We demonstrate a new procedure to synthesize covalently linked hyperbranched polyglycidol brushes on Si/SiO₂ surfaces via anionic ring-opening multibranching polymerization of glycidol at 110 °C. Optimization of the polymerization experiments by exploiting reinitiation cycles produced polyglycidol brushes with ellipsometric thickness values of up to 70 nm. ¹³C NMR spectroscopy analysis of cleaved polymer allowed the elucidation of the structure and degree of branching of the polymer.
