The invention discloses a polymer with emulsified water demulsification and coalescence functions, its preparation method and application. The polymer with emulsified water demulsification and coalescence functions is prepared from the following components: 100 parts of monomers, 1 to 5 parts of initiators, 0.5 to 3 parts of chain transfer agents and 100 to 900 parts of organic solvents, wherein , the monomer is composed of the following components: 5-40 parts of functional monomers containing amphiphilic molecular segments, 5-30 parts of acrylic monomers containing crosslinking groups, 10-60 parts of acrylate soft monomers and 0-40 parts of acrylate hard monomer. The polymer of the present invention has strong adhesion to various porous filter materials, and does not block the pores of the material after drying. After the emulsified water droplets contact and collide with the surface of the polymer, the emulsified water droplets will break and then coalesce to form large water droplets. It is easy to achieve separation and has wide application prospects in the field of oil-water separation. |
