METHOD FOR PRODUCING AQUEOUS RESIN DISPERSION

Japanese Patent JP3643304

B2

PROBLEM TO BE SOLVED: To provide a new industrially simple method for producing an aqueous resin dispersion forming a film excellent in water resistance.
SOLUTION: This method for producing the aqueous resin dispersion is characterized by comprising an initial polymerizing step of charging a part of a polymerizable monomer component comprising a polymerizable monomer having an acidic group and other polymerizable monomers copolymerizable therewith together with an aqueous medium and an emulsifying agent and polymerizing ≥80 wt.% of the charged polymerizable monomer component and a regular polymerizing step of adding the residual polymerizable monomer component and polymerizing the residual polymerizable monomer component, regulating the total amount of the polymerizable monomer having the acidic group used in the whole polymerizing step to 0.1-3 wt.% based on the total amount of the polymerizable monomer component used in the whole polymerizing step, using 3-30 wt.% of the polymerizable monomer component and using 35-100 wt.% of the polymerizable monomer having the acidic group in the initial polymerizing step.
