Vinylene carbonate modified olefin-norbornene copolymer microsphere and preparation method thereof

The invention discloses vinylene carbonate modified olefin-norbornene copolymer microspheres and a preparation method thereof. Vinylene carbonate modified olefin-norbornene copolymer is used as a core layer material to prepare a core layer rod, and polysulfone resin is used as a cladding layer material to prepare a cladding layer rod; the core layer rod is inserted into the cladding rod and is subjected to vacuum heat treatment to prepare a preform rod, primary fibers are obtained through hot drawing, the number of iterations of the primary fibers can be selected according to preparation requirements to obtain fibers of corresponding stages, and microspheres are prepared by utilizing the characteristic that fluid in the fibers is unstable. The microspheres prepared by the method have the physicochemical properties of excellent monodispersity, uniform particle size, smooth surface and the like, and the particle size of the microspheres is controllable from 50 nm to 2 mm. 本发明公开了一种碳酸亚乙烯酯改性烯烃-降冰片烯共聚物微球及其制备方法，以碳酸亚
