【摘要】 本文制备了[m₁P₁P₂]C₁及[m₁P₁C₂P₂][C₁C₂G₁2],并研究网状聚合物共混时两聚合物的混溶性、通过X射线透视及热力学特性的估算进行了检验、用经典的方法—蠕变实验来分析共混对链段运动的影响,并从蠕变特性求出滞后谱、另外应用热电松弛法分析共混对链段运动的影响、通过两种实验互相印证和补充,找出共混链段运动的规律,用以描述网状共混物的结构特性。更多还原

【Abstract】 IPN and semi—IPN are prepared by simultaneously synthesizing un saturted crosslinked polyester with polyglycerol—gycolether with its crosslinker PAPI, and linear polyetbelene oxide, respectively. The investigation in their optical properties, x-ray diffraction and calculations of the thermodynamic praperties show that both IPN and semi—IPN are homogeneous. The influence of the blending upon the motion of chain segments was explored by thermostimulated electrical analysis and exriments of creep.更多还原
