The emulsion polymer particles can be prepared by a simple process of emulsion polymerization, and have an advantage of relatively easily controlling a degree of crosslinking. In addition, when a quenching polymer composition is prepared by using the quencher including emulsion polymer particles, it is possible to prepare a molded article that does not degrade mechanical properties, such as impact strength and tensile strength, of existing thermoplastic polymers, has a fine appearance, and has an excellent quenching effect. In particular, an excellent quenching effect can be exhibited even in an extrusion process in which it has been conventionally difficult to achieve.
