✦ Synopsis

The synthesis of a diblock copolymer of styrene and vinyl acetate (VAC), PS-b-PVAC, was performed by successive photoinduced charge-transfer polymerization (CTP) under UV irradiation. A novel amphiphilic diblock copolymer of PS-b-PVA then was obtained by the hydrolysis of the diblock copolymer PS-b-PVAC with sodium ethoxide as a catalyst. Both of them were characterized by Fourier transform infrared, 1 H NMR, and gel permeation chromatography in detail. The effect of the solvents on the CTP and the kinetics of the CTP are discussed.

## Abstract Copper‐mediated atom transfer radical polymerization (ATRP) is versatile for living polymerizations of a wide range of monomers, but ATRP of vinyl acetate (VAc) remains challenging due to the low homolytic cleavage activity of the carbon‐halide bond of the dormant poly(vinyl acetate) (P
