酒精加入塑膠杯中會溶掉塑膠杯
為什麼啊?
請用化學性質或高分子方面來解釋哦!
謝謝大家

溶解條件:
1. Like disolves like: 酒精與塑膠的化學相似性而定
2. Crosslinking: 不會溶解
3. Crystallinity: 不易溶解
4. Molecular weight: 愈大不易溶解
5. Temperature: 不一定,視其溶解特性(UCST or LCST)
不過最簡易的方法視酒精與塑膠的溶解度參數(可參考,不一定完全正確)

酒精是屬極性溶劑,有強的氫鍵,你所指的塑膠應該含極性基.一般容器PET,PP,PC等不會溶於酒精.

像一般的衛生杯都是碳的分子鏈結購
太適合有機溶劑了
由於酒精是有機的活性界面劑,只要是碳氫氧的化合結構
所以跟有機化合物有親和力
另外還有石化液體如去漬油也對有機化合物有親和力
