Abstract: |
The invention is an epoxy functional cross-linked core-shell nano high molecular microsphere and its preparing method, using multiple alkene monomers and alkene monomers with epoxy functional groups as raw materials, on the condition of emulsifier and initiator, and preparing it by emulsion or suspension polymerization using water as medium; the product has a cross-linked structure inside both the core and shell, the core and shell are linked through chemical bonds, the epoxy functional groups are grafted on the microsphere surface, and the particle size is less than 100 nm. By changing the composition of the core and shell, it obtains an epoxy functional nano high molecular microsphere with mutiple different physico-chemical properties, and has very high freedom in selecting structure design. It solves the problem that the precious core-shell high molecular microshperes have no nano size and that the precious cores and shells are mostly linear polymers, and simultaneously by introducing epoxy functional groups on the surface, and improves the interface compatibility as this microsphere is filled in high molecular basal body, thus broadening its application field. |
