Branched or hyperbranched polymeric structures which contain at least one etherimide branch point, more specifically from stable A.sub.1 B.sub.n (where n.gtoreq.2), AB, AA, and BB monomers; A.sub.m end-capping agents (where m=1); B.sub.n cores (where n.gtoreq.1) and combinations thereof; with controllable degrees of branching (DB=0-1), molecular architectures, end-group compositions, along with methods for their preparation.
