Abstract
Provided are star-shaped non-vinyl polymers of a variety of compositions and a method for manufacturing such star-shaped polymers. The star-shaped polymers include a plurality of non-vinyl polymeric arms covalently linked to a crosslinked core. The core is made from crosslinkable non-vinyl reactants. The method involves reacting functionalized non-vinyl polymer pre-arms with the crosslinkable non-vinyl reactants.
