Abstract
The invention relates to a polymeric microsphere and a preparation method thereof, belonging to the technical field of high polymer materials. The polymeric microsphere comprises the following raw materials in parts by weight: oil phases: 10-20 parts of ethylene glycol dimethacrylate, 15-25 parts of pentaerythritol triacrylate, 50-60 parts of hydroxyethyl methylacrylate, 20-30 parts of butyl acrylate, 5-9 parts of styrene, 60-70 parts of xylene, 40-50 parts of isooctane and 2-8 parts of azodiisobutyronitrile; water phases: 3-10 parts of polyvinyl alcohol, 15-25 parts of gelatin, 50-60 parts of NaCl and 1000-2000 parts of deionized water. According to the preparation method, the polymeric microsphere which has hydroxyl groups and can be equipped with certain functional groups through further functional reaction is prepared by virtue of a suspension polymerization method by taking ethylene glycol dimethacrylate and pentaerythritol triacrylate as a mixing cross-linking agent and hydroxyethyl methylacrylate, butyl acrylate and styrene as copolymer monomers.
Description
technical field [0001] The invention relates to a microsphere material and a preparation method thereof. More specifically, the invention relates to a polymer microsphere and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] In addition to being used as a chromatographic separation filler, polymer microspheres, as a functionalized polymer intermediate, can prepare functional polymer separation materials with various functional groups through polymer chemical reactions. In addition to playing an important role in the separation of chemical components, it can also be used as a stationary phase for ion exchange, polar separation and size sieving in chromatographic separation. In the extraction and separation of Chinese herbal medicines, macroporous resins can selectively Absorbs active ingredients in herbs. Functionalized polymer microspheres can also play a role in biochemical aspects including the separation of...
