丙烯基苯化合物改性双马来酰亚胺树脂 Ⅰ.BPPDPS的合成、表征及预聚物的溶解性

Propenylphenyl Compound Modified BismaleimideResin (Ⅰ) Synthesis and Characterization of BPPDPS and Solubility of Prepolymer

合成了一种双丙烯基苯化合物—双（丙烯基苯氧基）二苯砜用于改性双马来酰亚胺。根据Ｗｉｌｉａｍｓｏｎ法合成了双（丙烯基苯氧基）二苯砜，并用元素分析、红外光谱、紫外光谱、核磁共振、质谱等方法进行了结构表征。测定了预聚物的溶解范围，获得了溶解性较好的混合溶剂，用于复合材料成型加工。

A propenylphenyl compound, bis(o-propenylphenoxy)sulphone was synthesized as a comonomer for bismaleimides. The compound was produced by Williamson method and characterized by Element Analysis, FT-IR, UV, 1 H-NMR and MS. And the solubility range of the BMI prepolymer was determined to get good solvents for composite fabrication.
