SYNTHESIS OF HYDROXY-TERMINATED POLY(VINYL ETHERS) BY LIVING CATIONIC POLYMERIZATION .2. POLY(2-CHLOROETHYL VINYL ETHER) - A TELECHELIC POLYMER WITH REACTIVE PENDANTS
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 degrees C and subsequent end-group transformation of the acetate (alpha-end) and aldehyde (omega-end) groups into hydroxy groups. The obtained polymers possess controlled molecular weights and narrow molecular weight distributions.
