  • Publication number: 20240199769
    Abstract: The present disclosure discloses a method of a functional monomer in emulsion polymerization, belonging to the field of synthesis of functional monomers and methods of emulsion polymerization. The present disclosure obtains functional monomers TDMAMA and TDMAIA by synthesis, which may show different functions at different pH. By adjusting an H+/OH? content in an emulsion with an acid and alkali solution at a certain concentration, it is found that the functional monomers are both an emulsifier, a polymerizing monomer, and a reducing agent at a specific pH, at which the emulsion is stable, and may perform free-radical emulsion polymerization at room temperature, and high molecular weight polymer is obtained through a branched polymerization. When an H+ concentration is less than OH?, the emulsion is unstable and has flocculation, then the polymerization terminates, and emulsion breaking can be realized without adding an additional emulsion breaker.
