    摘要： The specification discloses a process for producing poly-branched polymer having relatively high molecular weight by forming a first set of branches by polymerizing monomers which are either protected against or are non-reactive to branching and grafting during polymerization, grafting that first set of branches to a core having a plurality of reactive sites capable of reacting with the reactive end units of said branches, either deprotecting or activating a plurality of monomeric units on each of said branches to create branch reactive sites, forming a second set of branches in the same manner as the first set of branches were formed, grafting the second set of branches to the first set of branches by reacting the reactive end units of the second set of branches with each said branch reactive site on said first set of branches and repeating the foregoing steps reiteratively to form and attach subsequent sets of branches to prior branch sets until a desired number of iterations has been effected.
