The present disclosure obtains functional monomers TDMAMA and TDMAIA by synthesis, which may show different functions at different pH.

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.
