• 中文摘要： 由所測定之聚氯乙烯∕丁二烯?共聚物（含40％重量百分比之丙烯?）摻合物之蒸氣平衡吸收數據，計算聚合體間
  之交互作用參數，以這些參數值及利用穩定平衡溶液之準繩，得知此兩聚合物通常認為是親和對，但由熱力學之觀點看
  實為非親和對。由所測定此摻合體之動態機械性質之數據，計算它在玻璃轉移溫度的部份自由體積，其值較由加成規則
  計算所得之值低 40％ ，這亦顯示，此摻合物為非均質的。

• 英文摘要： Vapor sorption of the blends of poly (vinyl chloride) and poly (butadiene-co-acrylonitrile) contain-ing 40% by weight of acrylonitrile was studied. Calculations of the polymer-polymer interaction parameterusing the sorption data, the Scott's equation and the criterion for stable equilibrium solution showed thatthe polymer blends usually regarded as compatible are actually thermodynamically incompatible. Frac-tional free volumes of the blends calculated using measured dynamic mechanical data were found to beabout 40% lower than those calculated using the additivity rule, also indicating a heterogeneity.
