Graft copolymers were synthesized via grafting-through method by the quantitative synthesis of macromonomers via living cationic polymerization using vinyloxy group-containing alcohols as quenchers and subsequent cationic copolymerization of these macromonomers and an alkyl vinyl ether. The quenching of living cationic polymerization of isobutyl vinyl ether (IBVE) using methanol, ethanol, 2-propanol, and tert-butyl alcohol indicate that the primary alcohols are suitable for end functionalization due to the stability of the acetal ω-ends. Thus, macromonomers were prepared by the end-capping method using vinyloxy-containing primary alcohols as quenchers for the living cationic polymerization of IBVE under appropriate conditions. The spacer structure adjacent to the vinyloxy group of the macromonomer is highly important for the efficient cationic copolymerization that proceeded without side reactions. A macromonomer prepared from 1,4-butanediol monovinyl ether was successfully copolymerized with IBVE using an appropriate catalyst, yielding graft copolymers in high yields.
