        摘要：The state of research of hyperbranched polymers,which is very brisk recently in the domain of polymer chemistry,is introduced.It is pointed out that the hyperbranched polymers can be preparated by the polycondensation of the monomers with ABx funcationality or by selfcondension vinyl polymerization of the monomers with the general structure A = B - C*.At present the degree of branching and the molecular weight of hyperbranched polymers are characterized mainly by nuclar magetic resonance spectroscopy (NMR) and gel permeation chromatography (GPC). But there is a limit in the practical application of these mothods.
