Abstract
The present invention provides novel one-step processes for preparing highly branched macromolecule polymers that have highly controlled molecular architectures. The process comprise the reaction of a branching monomer such as a substituted phenyl compound having the formula: ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 are defined herein, with a second monomer (a core monomer) such as a dihydric phenol for a sufficient period of time and at a sufficient temperature to directly produce the highly branched polymer, characterized by having a single core, in a single processing step.
