| titleOfInvention | A kind of preparation method of the grade polyureas mono-dispersion microballoon of size tunable |
| abstract | The present invention relates to the preparation method of the grade polyureas mono-dispersion microballoon of a kind of size tunable.The method is with isocyanate ester compound as monomer, and the drop being extruded into by syringe needle or capillary tube is joined in the aqueous solution of water or polyamine and carries out precipitation polymerisation.Drop is in infall process, and its surface monomer reacts rapidly formation gel layer or sclerderm with water or polyamine, maintains stablizing of particle.The method is with water as disperse medium, pollution-free；Polyreaction can be carried out at a lower temperature, and equipment is simple, and production cost is low.Without residual monomer in thus obtained microsphere, post processing is simple.The inventive method, without any surface modification and porogen, settles the porous polyurea microsphere of prepared rich surface amino-contained at one go, can be used for enzyme fix, the absorption of chemical catalysis, dyestuff and heavy metal ion with the field such as separate. |
