Abstract
Toughened polymeric materials and methods of forming toughened polymeric materials are provided herein. In some embodiments, a method of forming toughened polymeric materials may include preparing a branched polymeric additive; mixing the branched polymeric additive with a polymer to form a polymeric mixture, wherein the branched polymeric molecule either mixes and/or bonds with the polymer to reduce mobility in the polymer; and curing the polymeric mixture. In some embodiments, a toughened polymeric material comprises a polymer network; and a branched polymeric molecule bonded to the polymer network.
