    摘要: A process for the synthesis of branched graft polymers comprises acylating a first polymer and grafting thereto a second polymer, the second polymer having reactive groups capable of being bound to the acyl groups on the first polymer. The acylation and grafting steps can be repeated to produce graft polymers having a dendritic architecture. The invention also provides polymers produced by the above process, which may be simple branched (comb) polymers, or dendritic polymers.
