Title:
Porous polymer microspheres with optical anisotropy, method of manufacturing the same and application of the same
Document Type and Number:
WIPO Patent Application WO/2019/128838
Kind Code:
A1
Abstract:
Porous polymer microsphere having radial optical anisotropy and diverse swelling states when dispersed in different solvents, which have ability to well swell the porous microspheres. A method for preparing the porous polymer microspheres, including: forming a homogeneous liquid crystal mixture; dispersing the liquid crystal mixture into a continuous phase to form a emulsion of liquid crystal droplets; polymerizing the at least one reactive liquid crystal to form intermediate microspheres; removing the at least one non-reactive liquid crystal compound to form the porous polymer microspheres; separating, washing and dispersing or drying the porous polymer microspheres. The polymer microspheres can be used as the stationary phase in chromatograph separation, improving separation efficiency and column packing efficiency.
