Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a temperature-sensitive polymer which shows temperature responsiveness having a lower critical solution temperature, and is present stably in a particulate state in water and/or an organic solvent, and to provide a coating composition which has excellent temperature responsiveness when the temperature-sensitive polymer is added as a fluidity adjusting agent to the coating composition.SOLUTION: The temperature-sensitive polymer is provided which shows temperature responsiveness having a lower critical solution temperature, and is present stably in a particulate state in water and/or an organic solvent, and in which a polymerizable unsaturated monomer constituting the polymer contains an N-substituted (meth)acrylamide derivative and/or vinyl methyl ether. The coating composition containing the temperature-sensitive polymer is also provided.SELECTED DRAWING: None 【課題】下限臨界共溶温度を有する温度応答性を示し、水及び／又は有機溶媒中において、粒子状態で安定的に存在する感温性重合体を得ること、並びに該感温性重合体を流動調整剤として添加した場合に優れた感温応答性を有する塗料組成物を提供すること。【解決手段】下限臨界共溶温度を有する温度応答性を示し、水及び／又は有機溶媒中において、粒子状態で存在することを特徴とする感温性重合体であって、重合体を構成する重合性不飽和モノマーが、Ｎ置換（メタ）アクリルアミド誘導体及び／又はビニルメチルエーテルを含有することを特徴とする感温性重合体、並びに該感温性重合体を含有する塗料組成物。【選択図】なし
