| 摘 要： | 采用红外光谱、紫外光谱、流变仪、GPC和1H-NMR等手段,探讨质子酸催化漆酚聚合的反应历程。结果表明,在质子酸的作用下,漆酚不饱和侧链的双键与质子酸的H+发生亲电加成,并形成碳正离子,该碳正离子与漆酚苯环发生Friedel-Crafts烷基化反应,从而生成漆酚聚合物。

| Abstract: | Reaction process of polymerization of urushiol catalyzed by bronsted acid was discussed by UV,IR,GPC,1H-NMR and Rheometer. Results showed the electrophilic addition reaction was took place between H+ and the double bond of the urushiol unsaturated side chains,and formed carbocation which made urushiol gradually forming polymer with bezene of urushiol through the reaction of Friedel-Crafts alkylation. |
