Abstract
Branched, dendrimeric macromolecules having a central nucleus and a series of polyoxaalkylene chains that radiate from the nucleus and spread into the surrounding space branching a cascade fashion until the desired size results. Molecules formed in this manner are free of excessive functional crowding on their outer surfaces. Synthetic methods of preparing these molecules and their uses are described.
