| 中文摘要 | hyperbranched vinyl polymers were prepared by reversible addition-fragmentation chain transfer ( raft) polymerization of a styrenic asymmetric divinyl monomer. this was achieved by using cumyl dithiobenzoate or s-dodecyl-s'-(alpha,alpha'-dimethyl-alpha ''-acetic acid) trithiocarbonate as the chain transfer agent, 1,1'-azobis(cyclohexanecarbonitrile) or thermal initiation as a source of radicals. cross-linking was inhibited by a rapid raft-based equilibrium between active propagation chains and dormant species, and thus a hyperbranched polymer with a monomer conversion as high as 80% was obtained. the hyperbranched structure and properties of the resultant polymers were characterized by a combination of h-1-nmr spectroscopy and a triple detection size exclusion chromatography (tri-sec). the hyperbranched vinyl polymer has a broad molecular weight distributions and a low mark-houwink exponent alpha value compared with the linear counterpart. |
