摘要
Abstract
Hyperbranched epoxy-based chain extenders were synthesized via self-condensation ring-opening polymeriza-tion using stearic acid(HSt)and triglycidyl isocyanurate(TGIC)as raw materials.The effects of synthesis parameters,including reactant molar ratio,reaction temperature,and reaction time,on the molecular structure,thermal properties,and molecular weight of the resulting chain extenders were systematically investigated.The obtained products were char-acterized by Fourier transform infrared spectroscopy,¹³C nuclear magnetic resonance spectroscopy,thermogravimetric analysis,and differential scanning calorimetry.The results confirm the successful preparation of hyperbranched epoxy-based chain extenders.Optimal synthesis conditions are identified as follows:HSt-to-TGIC molar ratio of 8∶2,reaction temperature of 150℃,and reaction time of 2.5 h.Under these conditions,the resulting chain extender exhibits desirable structural characteristics and thermal stability,demonstrating its potential for practical applications in polymer modifica-tion.关键词
