[0024] Examples:
[0025] The invention relates to a synthesis process of a binary copolymer antifouling agent based on controlling the stirring time, including the following steps:
[0026] (a) First, prepare the chelating group monomer and acrylamide in a certain proportion;
[0027] (b) Add the chelating group monomer and acrylamide into the reaction vessel, and then add the solvent to dissolve, then add the catalyst;
[0028] (c) Stir to make it fully mixed evenly;
[0029] (d) Place it in a water bath and stir at a certain temperature for 30-50 minutes to react to obtain a reaction product mixture;
[0030] (e) The reaction product mixture is cooled and filtered, the filtered liquid is distilled under reduced pressure, and the target product is obtained after separation.
[0031] The reaction vessel is a beaker.
[0032] In the step (e), filtration treatment is performed through molecular sieve.
[0033] In the step (e), vacuum distillation is performed by a rotary evaporator.
