中文摘要 | 聚苯乙烯及聚乙酸乙烯酯中引入荷電體可改變此類高分子和摻合高分子的物性與機械性質,其軟化點與玻璃轉移點剛隨著荷電體含量的增加而升高。由動態機械分析顯示,此摻合物之損失模數(Loss modulus, E”)轉移峰將隨著摻合物內相反荷電體含量之增加而向此二高分子的玻璃轉移溫度之間移動而產生一寬廣的轉移峰。由掃描電子顯微照片顯示,此摻合物不含荷電體時為兩分離相;聚苯乙烯相懸浮於聚乙酸乙烯酯之連續相中,且聚苯乙烯相因大小隨相反荷電體含量的增加而減小。當相反荷電體含量超過10莫耳百分比時,此摻合物則呈現一均勻之相。 |
英文摘要 | The introduction of charge group into polystyrene and poly(vinyl acetate) chains had significantly influenced the physical and mechanical properties of the resultant polymers and the polyblends. The softening point and glass transition temperature of the resultant polymers were increased with an increase of the charge group content in the polymers. The results from dynamic mechanical analysis showed that the transitional peak of loss modulus-temperature curve of the ionomeric blends shifted inwardly to a temperature between the two glass transition temperatures of the straight polymers as the charge group content increased showed two-separated phases for the blend of polystyrene and poly(vinyl acetate). Polystyrene was the dispersed phase in the poly(vinyl acetate) matrix. However, the domain size of the dispersed phase became smaller and smaller as the charge group content increased in the inonomeric poylblend. A homogeneous phase was fond as the content of charge groups exceeded 10 mole% in the ionomeric polyblends. |
