聚酰亚胺和聚苯硫醚耐甲烷氯化物的研究

Resistance of polyimide and polyphenylene sulfide to methane chloride

探究了聚酰亚胺、聚苯硫醚耐甲烷氯化物腐蚀的效果。通过质量变化和液相色谱研究了2种高聚物的耐蚀性。结果表明:聚酰亚胺在二氯甲烷、三氯甲烷中很快被溶解,在四氯甲烷中微量溶解;聚苯硫醚在二氯甲烷中微量溶解,在三氯甲烷、四氯甲烷中有溶胀现象发生。

The resistance of polyimide,polyphenylene sulfide to methane chloride were explored.Weighing and liquid chromatography were applied.The results showed that：the polyimide was dissolved in dichloromethane,trichloromethane quickly and in small amount in tetrachloromethane.Polyphenylene sulfide was dissolved in small amount in dichloromethane,the swelling was occurred in the trichloromethane and tetrachloromethane.
