英文摘要three-arm and four-arm star-like polybutadienes (pbds) were synthesized via the combination of living anionic polymerization and the click coupling method. kinetic study showed that the click reaction between the azido group terminated pbd-t-n-3 and the alkyne-containing multifunctional linking reagent was fast and highly efficient. all coupling reactions were fully accomplished within 40 min at 50 a degrees c in toluene in the presence of the reducing agent cu(0), proven by h-1-nmr, ftir and gpc measurements. for the coupling reactions between the pbd-t-n-3 polymer and dialkyne-containing compound, the final conversion of the coupled pbd-pbd polymer was ca. 97.0%. when a pbd-t-n-3 polymer was reacted with trialkyne-containing or tetraalkyne-containing compound, the conversion of three-arm or four-arm pbd was around 95.5% or 87.0%, respectively. several factors influencing the coupling efficiency were studied, including the molecular weight of the initial pbd-t-n-3, arm numbers and the molar ratio of the azido group to the alkynyl group. the results indicated that the conversion of the target products would be promoted when the molecular weight of the pbd-t-n-3 was low and the molar ratio of the azido to alkynyl groups was close to 1.
