(57) Abstract: In a reusable fiber composite material in which fibers are bonded to each other using a polymeric binder, not only the fibers but also the binder itself is reused in the original manufacturing method. PROBLEM TO BE SOLVED: To provide an aqueous addition polymer dispersion liquid containing an addition polymer fraction which forms a film at a use temperature in a dispersed state, and at that time, a dispersion which forms a film at a use temperature. The total amount of the addition polymer fraction of the dispersion of the aqueous addition polymer contained in the aqueous polymer dispersion in the state of the binder is converted to the aqueous addition polymer solution when the pH of the aqueous dispersion medium changes.
