超速离心沉降法分子式:CAS号:性质:利用离心力的作用将分散体系中的分散质点逐渐沉降,质点越大,沉降速度越大,基于沉降速度与分子量依赖性的原理,来测定高聚物分子量分布的方法。在高分子溶液中,高分子的质量很小,需要超速离心机,在很大的离心力场下才能观察到它们的沉降。离心机转速可达1000r/s以上,得到几十万倍于重力的离心力。超速离心沉降法测量分子量分布,是测定其沉降系数S,S的定义为粒子在单位离心加速度场中的沉降速率,表达式如下: 式中为粒子的沉降速率;r为界面在转轴中心的距离;w为转动角速度。此法适用于分子量1×104~2×107的范围,能获得各种平均分子量。由于S有浓度依赖性,最好选择θ溶剂,溶剂与溶质的折射率差及密度差要足够大。
