玉米油基热固性树脂的制备与性能研究

The Synthesis and Properties of Thermosetting Resins Based on Corn-oil

使用玉米油在一定条件下先后与甘油和马来酸酐及苯乙烯形成热固性树脂。实验通过红外光谱、热失重和动态力学分析对共聚物进行了表征。研究表明,该树脂具有热固性树脂的典型变化行为,该树脂热稳定性随着玉米油单甘油马来酸单酯的增加而降低,存储模量和交联密度随着苯乙烯质量分数的增加分别增加和减小。

This paper,use the corn-oil,glycerin and maleic anhydride（MA）and styrene to form thermosetting resins under certain conditions.And by FTIR,TG and DMA,the polymers were characterized.The results showed that the thermosetting resins had their typical changes in behavior.Study also showed that the thermal stability of resin decreased with the COMG increased,and with the styrene concentration increased,the storage modulus increased and the crosslink density decreased.
