补充资料:稳定单相极限曲线
分子式:
CAS号:
性质:二元共混体系的温度-组成相图中,单相区域与二相区域的分界线称为稳定单相极限曲线。这一分界线上的各点表示二元共混体系(包括二元聚合物共混体系》中二相体系稳定性的极限。如果二元体系的相容性随温度升高而增加,那么稳定单相极限曲线就呈现为一极大曲线,即存在一最高临界共溶(或共容)温度,高于这一温度时,两组分在所有组成范围都是相容的。这种情况下,将共混体系从稳定单相极限曲线之上某一点冷却至其下某一点,体系将以一种“成核”和“生长”过程发生相分离。然而对于聚合物共混体系,这种相分离可能推迟。相反的情况,如果二元体系的相容性随温度升高而下降,那么稳定单相极限曲线就呈现为一极小曲线,即存在一最低临界共溶(或共容)温度,低于这一温度时,两组分在所有组成范围都是相容的。
