ORGANIC-DETERIORATED-MATERIAL SCAVENGER

PROBLEM TO BE SOLVED: To provide a low cost organic-deteriorated-material scavenger that can further improve the adsorptivity, dispersibility and stability to the carbon residues or the sludges produced by alteration or oxidation or the like resulting from heating treatment, pressurizing treatment, foreign matter contamination, or atmosphere gas's oxygen, SO, NO, etc. in the lubricator comprising resin liquid or plasticizer, that can remove said insoluble organic-deteriorated-materials, and that has a versatility and can easily be manufactured.SOLUTION: The organic-deteriorated-material scavenger comprises: a polymer that is at least any of nitrogen-containing polymer obtained by polymerizing nitrogen-containing monomer having an unsaturated group and at least any nitrogen-containing group selected from amino group, ammonium group and nitrogen-containing heterocyclic group, and nitrogen-containing polymer obtained by polymerizing imine monomer and having an imino group as the nitrogen-containing group, and that has a weight average molecular weight of 300 to 100,000; and at least any nitrogen-containing substance of amine compounds represented by RRRN (1). 【課題】樹脂液や可塑剤を含む潤滑剤中における加熱処理、圧力処理、異物混入、雰囲気ガスの酸素、ＳＯ３、ＮＯＸ等による変質や酸化等によって生じたカーボンかすやスラッジに対する吸着性、分散性、安定性を一層向上し、これらの不溶性の有機劣化物を除去することができ、汎用性を有し簡便に製造することができる安価な有機劣化物除去剤を提供する。【解決手段】有機劣化物除去剤は、アミノ基、アンモニウム基、及び窒素含有複素環基から選ばれる少なくとも何れかの窒素含有基と不飽和基とを有する窒素含有単量体が重合した窒素含有重合体と、イミン単量体が重合しイミノ基を窒素含有基とする窒素含有重合体との少なくとも何れかでありその重量平均分子量を３００〜１００，０００とする重合体、及びＲ１Ｒ２Ｒ３Ｎ ・・・（１）で示されるアミン化合物の少なくとも何れかの窒素含有物質を含んでいる。【選択図】なし
