摘要
对用稀溶液粘度法确定不同高分子之间混溶性的Δ b判据、α判据和Δ [η]判据进行了深入的研究 ,发现三者虽然形式上有所不同 ,但是都从不同的侧面反映了不同高分子之间相互作用参数 k AB的值对不同高分子之间混溶性的影响。Δ [η]判据实际上反映的是 k AB绝对值的大小对不同高分子之间混溶性的影响 ;而Δ b判据和α判据反映的是 k AB相对值大小对不同高分子之间混溶性的影响。文章用Δ b判据和Δ [η]判据对聚甲基丙烯酸甲酯 (PMMA )和聚醋酸乙烯酯 (PVAc)在不同溶剂中的粘性行为进行了研究 。
Investigation on the criteria Δ b, α and Δ[η] available to the determination of polymer-polymer compatibility by viscosity measurement indicates that, though not the same in form, these criteria chiefly depend upon the Huggins mutual interaction parameter k AB . The influence of absolute value of k AB upon polymer-polymer compatibility can be indicated by Δ[η] criterion, whereas the influence of relative value of k AB upon polymer-polymer compatibility can be indicated by Δb and α criteria. Both Δb criterion and Δ[η] criterion were employed in this article to study the compatibility between poly(methyl methacrylate) (PMMA) and poly(vinyl acetate) (PVAc).
