To provide a quenching agent containing polymer particles, a quenching polymer composition comprising the same and a method for producing the same.SOLUTION: There is an advantage that the polymer particles can be produced by a simple step of an emulsion polymerization method and the degree of crosslinking can also be relatively easily adjusted. Further, when a quenching polymer composition is produced using a quenching agent containing the polymer particles, a molded article having an excellent quenching effect while having beautiful appearance can be produced without deteriorating mechanical properties such as the impact strength and tensile strength of the conventional thermoplastic polymer, in particular, an excellent quenching effect can be exhibited even in extrusion processing which was conventionally difficult to achieve.SELECTED DRAWING: None 【課題】重合体粒子を含む消光剤、これを含む消光性高分子組成物及びこの製造方法を提供する。【解決手段】重合体粒子は、懸濁重合法の簡単な工程により製造することができ、比較的架橋度の調節が容易であるという利点がある。また、前記重合体粒子を含む消光剤を使用して消光性高分子組成物を製造する場合、従来の熱可塑性高分子の衝撃強度及び引張強度のような機械的な特性を低下させることなく、綺麗な外観を有しながらも、優れた消光効果を有する成形品を製造することができ、特に、従来は達成することが困難であった押出加工においても、優れた消光効果を発現することができる。【選択図】なし
