Synthesis and micelle formation of fluorine-containing block copolymers

摘要

Fluorine-containing block copolymers composed of poly{2-(2,2,3,3,3-pentafluoropropoxy)ethyl vinyl ether)} (polyPFPOVE) and poly(2-hydroxyethyl vinyl ether) (polyHOVE) were synthesized and their micelle formation in water was investigated. The block copolymers were prepared by sequential polymerization of PFPOVE and 2-acetoxyethyl vinyl ether (AcOVE), followed by hydrolysis of the acetyl-protecting group. The surface tension of the block copolymer solution decreased to ca.32 mN/m. The experimental data of the small-angle X-ray scattering (SAXS) measurement of 1 wt% aqueous polymer solution were well-reproduced by the calculated scatting curves for core-shell micelle models.
