摘要： The present invention relates to masterbatches useful for modifying thermoplastic polyesters, in particular to masterbatches comprising dispersed chain coupling agents, such as for example dianhydrides and optionally a polyol branching agent. The invention also relates to a method for preparing the masterbatches, and to a method for modifying a polyester utilizing the masterbatches. Yet another aspect of the invention is the use of such a masterbatch composition for the modification of polyesters.
