Preparation of Organic Polymer Chromatographic Packings by Swelling Seeds and Their Application for Seperation of Salidroside

Monodisperse polystyrene particles as the swollen seeds for synthesizing macroporous(poly(styrene-)co-divinylbenzene) organic polymer chromatographic packings were prepared by dispersion polymerization in n-butanol reaction media.And the stable fine emulsions for swelling seeds could be obtained by using a high-pressure homogenizer.The chromatographic packings exhibit excellent monodispersibility and low back pressure while packed into chromatographic column,and can be employed for the separation and purifi...
