Functional monomers are monomers that provide specific functional groups. For example: anti-pollution, solvent resistance, water resistance, light and color retention, etc. Functional monomers are: surface active monomers, self-crosslinking functional monomers, water-soluble monomers, etc. There are two commonly used functional monomers: MAA methacrylic acid and acrylamide. Functional monomer selection: The functional monomer is selected according to the structure or functional group of the imprinted molecule. It must be able to interact with the imprinted molecule and be in a proper position with the crosslinking agent molecule in order for the imprinted molecule to obtain the desired orientation and positioning.
The monomers are generally unsaturated, cyclic, or low-molecular compounds containing two or more functional groups. For example, vinyl chloride CH2=CHCl monomer can be polymerized to form polyvinyl chloride; caprolactam monomer can be polymerized to form polycaprolactam. For example, ethylene, propylene, vinyl chloride, styrene, etc. are the monomers that synthesize polyethylene, polypropylene, polyvinyl chloride, and polystyrene, and also constitute the structural units of these four polymer compounds.
