摘要

介绍了近年来在高分子化学领域内十分活跃的高支化聚合物研究的状况。指出通过ABx 型单体的缩聚反应和A=B-C

型单体的自缩合乙烯基聚合都可获得高支化聚合物。目前用以表征高支化聚合物支化度和分子量的方法主要为核磁共振法和凝胶渗透色谱法，在实际应用中都存在局限性。

Abstract

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.
