The living cationic random copolymerization of MVE and CEVE to obtain functionalized thermo‐responsive PMVE as precursors for more complex PMVE‐containing polymer structures is reported. The random copolymers P(MVE‐co‐CEVE) were synthesized at 0 °C in toluene using the DEE/TMSI/ZnI2 initiating system. The monomer reactivity ratios of these copolymers are determined according to the extended Kelen‐Tüdõs procedure: rCEVE = 0.48 ± 0.04 and rMVE = 0.76 ± 0.05. The cloud point temperatures of the random copolymers are found to depend strongly on the composition of the copolymer and disappeared at CEVE contents above 3 mol‐%. magnified image
