| 摘 要： | 本文用傅里叶交换红外光谱法（ＦＴＩＲ）表征了苯乙烯－甲基丙烯酸共聚物Ｐ（Ｓ－ＭＡＡ）和聚环氧丙烷（ＰＰｒＯ）共混体系的相容性．用谱带分离的技术比较准确地测定了共混体系中几种羰基的吸光系数比，并且用简明的方法定量计算了它们之间平衡的平衡常数．同时实验还表明共混组分中聚醚的分子量、分子结构、Ｐ（Ｓ－ＭＡＡ）中ＭＡＡ的含量以及共混组分的比例和体系的相容性有密切的关系．

| Abstract: | Mikibility of styrene-methacrylic add copolymer P(S-MAA) with polypropylenechide PPrO were studied by means of FTIR. Some kind of carbonyl absorptivityraho in blends were given through curve-fitting technique and equilibrium constantsbetween varying carbonyls were calculated by simple way.The results show thatmiscibilty dpends on MAA content in P(S-MAA),the moledar weight andsic of polyether and compesihon of blends. |
