摘要：

Three-dimensional star-branched poly(epsilon-caprolactone) was synthesized by combining ring-opening polymerization and "living" free-radical polymerization. The "arm-first" approach was used. In the first step the functionalized poly (epsilon-caprolactone) was synthesized as the side chains. Then a difunctional monomer, divinylbenzene (DVB), was used as end-linking agent to synthesize star-branched polymers via "living" free radical polymerization. The star-branched poly(epsilon-caprolactone) with divinylbenzene core was characterized by gel permeation chromatography (GPC), proton nuclear magnetic resonance (H-1 NMR), and differential scanning calorimetry (DSC).
