Abstract
A new class of branched dendrimeric macromolecules, is described essentially consisting of a polyvalent central nucleus and a series of polyoxaalkylene 'dendra'. Such molecules are characterized by the presense of at least one branch, attached either directly to the 'core' or to a 'dendron', which does not participate in the growth and which therefor differs from all the other functions of the macromolecule.
