Abstract
An exchange reaction of hydroxyl and alkoxysilane is used as a polymerization avenue yielding hyperbranched polymers. A monomer containing hydroxy alcohol functionality and alkoxy functionality attached to a silicon atom in the monomer is employed, and a simple exchange reaction with driving off of alcohol by-product leads to the desired hyperbranched polymerization and materials.
