Synthesis of hydroxy‐terminated poly(vinyl ethers) by living cationic polymerization, 2. Poly(2‐chloroethyl vinyl ether): a telechelic polymer with reactive pendants

Abstract Hydroxy‐terminated telechelic poly(2‐chloroethyl vinyl ether) (poly(CEVE)) was synthesized by water‐based end‐capping reaction of living poly(CEVE) with the initiating system CH3CHClOCH2CH2OCOCH3/ZnCl2 in CH2Cl2 at −40°C and subsequent end‐group transformation of the acetate (α‐end) and aldehyde (ω‐end) groups into hydroxy groups. The obtained polymers possess controlled molecular weights and narrow molecular weight distributions.
