Novel　epoxide-terminated　hyperbranched　polyurethanes　(EHPU)　with　different　epoxy　values　were　prepared　through　functionalization　of　hyperbranched　polyurethane　with　glycidol.　Fourier　transformed　infrared　(FTIR)　and　nuclear　magnetic　resonance　analyses　were　conducted　and　confirmed　the　successfully　synthesis　of　EHPU.　Differential　scanning　calorimetry　measurements　were　carried　out　for　thermal　and　kinetic　studies　of　EHPU　and　benzoxazine　(BZ)　hybrid.　Specifically,　through　kinetic　study　using　advanced　isoconversional　method,　it　was　found　that　EHPU　can　catalyze　the　polymerization　of　BZ　oligomers　when　degree　of　curing　is　below　0.7　with　the　apparent　activation　energy　dropped　8.3　kJ/mol.　Whereas,　the　epoxide　groups　of　EHPU　can　join　the　curing　reaction　of　BZ　at　180　A　degrees　C,　which　was　further　confirmed　by　FTIR　analysis.
