Abstract： |
The present invention is the preparation process of functional composite nano carboxyl polymer/silica material, and belongs to the field of polymer material technology. The materials including nano SiO2 grain, coupling agent, organic olefin and olefin monomer containing carboxyl or carboxylate radical are produced into the functional composite nano carboxyl polymer/silica material through polymerization in soap-less emulsion or suspension with water as medium. The product is spherical grain with inorganic nano SiO2 as core, organic olefin polymer as shell and carboxyl radical as surface functional group, and has granular size smaller than 100 nm, very high chemically reacting activity and thus high application value and wide application range, especially in nano technology. |
