摘要：

The present paper focuses on the atom transfer radical polymerization (ATRP) of vinyl ether (VE) based macromonomers with a methacryloyl group at the chain end. Living cationic polymerization of isobutyl VE (IBVE) initiated with the HCl adduct of a VE carrying a pendant methacryloyl group in conjunction with ZnI2 yielded the macromonomer (MA-PIBVE) with a narrow molecular weight distribution (MWD) ((M) over bar(w)/(M) over bar(n) < 1.1). The ATRP of MA-PIBVE was carried out using a halide initiator and the CuBr/3,4'-di-n-heptyl-2,2'-bipyridine catalytic system. The number-average molecular weight of the polymacromonomer increased in proportion to the monomer conversion, while the MWDs stayed fairly narrow ((M) over bar(w)/(M) over bar(n) similar to 1.2). Thus a novel type of polymacromonomers with controlled chain lengths for both the backbone and the side chain have been synthesized through a combination of living cationic polymerization and ATRP techniques.
