采用乙烯基自缩合聚合制备了具有高度支化结构和大量活性基团的树枝状聚合物。如果乙烯基单体含有可以通过外部刺激的作用转化为起始部分的侧基，则其将进行自聚合。自聚合将经典乙烯基聚合方法的特征与缩聚的特征相结合，因为生长是通过反应性低聚物的偶联来完成的。通过3-（1-氯乙基）-乙烯基苯的聚合，获得了具有多种反应性官能团的高度支化的、不规则的树枝状结构。
Self-condensing vinyl polymerization was used to produce dendritic polymers with both highly branched structures and numerous reactive groups. A vinyl monomer will undergo self-polymerization if it contains a pendant group that can be transformed into an initialing moiety by the action of an external stimulus. The self-polymerization combines features of a classical vinyl polymerization process with those of a polycondensation because growth is accomplished by the coupling of reactive oligomers. Highly branched, irregular dendritic structures with a multiplicity of reactive functionalities are obtained by polymerization of 3-(1-chloroethyl)-ethenylbenzene.
