在之前的论文（1, 2）中，我们已经证明界面大分子的稳定性和能量不仅取决于界面的类型和大分子的整体构型，还取决于单体单元的构成。因此，我们认为将我们的研究扩展到由不同大分子组成的混合二维薄膜，以便将混合物的能量与组分聚合物的相应能量进行比较是特别合适的。特别是，选择了以下系统：（a）聚甲基丙烯酸甲酯-聚甲基丙烯酸乙酯（PMMA/PEMA）；（b） 聚甲基丙烯酸甲酯-聚甲基丙烯酸丁酯(PMMA/PBMA)；(c)聚甲基丙烯酸乙酯聚甲基丙烯酸丁酯(PEMA/PBMA)。选择这些大分子不仅是因为它们的二维态扩散稳定性，而且还因为它们都含有相同的“锚定”基团并且仅单体单元的链长度不同。
In previous papers (1, 2), we have shown that the stability and the energies of macromolecules at an interphase depend not only on the type of interphase and the bulk macromolecular configuration, but also on the constitution of the monomeric unit. Therefore, we deemed it particularly opportune to extend our investigation to mixed bidimensional films composed of different macromolecules in order to compare the energies of the mixtures with the corresponding energies of the component polymers.In particular, the following systems were chosen:(a) Polymethylmethacrylate-polyethylmethacrylate (PMMA/PEMA);(b) polymethylmethacrylate-polybutylmethacrylate (PMMA/PBMA);(c) polyethylmethacrylatepolybutylmethacrylate (PEMA/PBMA). These macromolecules were chosen not only for their bidimensional state spreading stability but also because they all contain the same" anchoring" groups and differ only in the length of the chain of the monomeric unit.
