    Abstract: 我們用一般的溶劑摻合方式,將兩相及三相高分子(Phenoxy /PVPh/PVP)混合均勻,並在玻璃片上成膜,將成膜的高分子混合物進行DSC的測量。由結果得知PVPh與Phenoxy完全不相容,而PVP與PVPh及Phenoxy兩者均相容,由於我們所使用的PVP有分子量為55,000g/mol的PVP2及分子量為360,000g/mol的PVP3,因此我們設計了兩個三相混合系統(Phenoxy/ PVPh/PVP2及Phenoxy /PVPh/PVP3)來探討PVP2與PVP3何者對Phenoxy/PVPh有較佳的共容性。
    在Phenoxy/ PVPh/PVP2系統中,PVP2含量高時(75wt﹪),三者可完全相容,其餘均不互容;而Phenoxy/ PVPh/PVP3系統中,相容的區域主要是發生在PVP3與PVPh比例高而Phenoxy 比例低時,而且在PVPh/Phenoxy比例固定時,PVP3含量的增加,可以提高三者的相容性。
