Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for recovering polymer powder with a high yield, with which quality of the polymer is not deteriorated and occurrence of fine powder can be suppressed in recovering the polymer powder from a latex including the polymer having high glass transition temperature. SOLUTION: In the method for recovering the polymer powder, the latex including the polymer (A) having glass transition temperature of 90°C or higher is made to coagulate by using a coagulant in the presence of at least one kind of compound (B) selected from a hindered phenol-based compound (b1) and a thiol compound (b2).
