中文摘要	n-Dodecylamine was used as reaction terminator to control the molecular structures of amine terminated hyperbranched(poly(ester-amine)s)(HPEA) synthesized from phthalicdiglycol diacrylate and 1-(2-aminoethyl)piperazine at molar ratio of 1:1 by Michael addition reaction.From the()~1H-NMR spectra of HPEA,the degree of branching increased and the amino active hydrogen content decreased with prolonging the reaction time.HPEA were further cured with β-glycidyloxylpropyl trimethoxysilane under ambient condition.The highest gel content and best mechanical properties of the cured coatings at active hydrogen and epoxy group stoichiometric ratio of 1∶1 can be attributed to the stepwise curing process,involving the fast reaction between amino active hydrogen and epoxy groups,and the slow hydrolysis and self-condensation of methoxysilane groups.; 国家自然科学基金(基金号20204005,50233030)资助项目
