酚氧树脂/聚(4-乙烯基吡啶)高分子复合物的制备及表征

Preparation and Characterization of Phenoxy Resin/ Poly(4 vinylpyridine) Interpolymer Complexes

采用元素分析、ＤＳＣ、ＦＴＩＲ、紫外光谱及ＸＰＳ等手段对酚氧树脂和聚（４－乙烯基吡啶）在氯仿中溶液共混形成的高分子复合物的组成及结构进行了研究，并与相应的共混物作了比较．结果表明，所得的各复合物的组成相同，其值与组分分子中的链节等摩尔比一致；而共混物也为相容体系，其组成与两高分子组分的投料比对应．基于实验结果，揭示了复合物的形成过程．

The compositions and structures of interpolymer complexes formed by mixing phenoxy resin (PHEB) and poly(4 vinylpyridine) (P4VPy) in chloroform have been studied by means of elemental analysis, DSC, FTIR, UV and XPS. In the meantime, the corresponding blends prepared have been characterized and compared. The results show that compositions of the complexes were identical with the ratio of equimolar interactive units. All blends were miscible and their compositions were related to the feed ratios. Based on the experimental results, process of formation of the complex is depicted.
