摘要
采用共混、模压的方法利用热固性反应树脂(PME)原位固化反应制备了高黏度的聚丁二酸丁二醇酯(PBS)。结果表明,PME交联网络的形成可以使PBS的黏度得到明显提高。采用扫描电子显微镜研究了复合材料的相形态及相容性,表明复合材料存在相分离,是不相容的体系。差示扫描量热测试表明,随着PME含量的增加,复合材料的结晶度先上升后下降;从复合材料拉伸曲线可以明显地发现,加入少量PME可以使复合材料发生从脆性到韧性的转变。
High-viscous poly （ butylene succinate ） （ PBS ）was prepared by means of blending and moulding, which was related to thermosetting reactive resin （ PME ） in situ.The results showed that the form of crosslinked network by PME could obviously improve the viscosity of PBS.Scanning electron microscope was employed to investigate the phase morphology and compatibility of the composites, the results revealed that they were immiscible but nevertheless showed some degree of adhesion between the two phases.Results of DSC showed that with the increase of PME, degree of crystallinity first rose then droped.As it clearly illustrated in stress strain curve, composites were deformed from brittleness to ductility by adding small amount of PME.
