Zusammenfassung:To provide a polymer dispersant that reduces the slurry viscosity of oil dispersions to enhance coatability and moldability, and improves the workability of halogen-based resin compositions to enhance low-temperature flexibility.SOLUTION: The present invention relates to a polymer dispersant for non-aqueous solvents, the polymer dispersant comprising a constituting unit derived from a monomer represented by general formula (1) and a constituting unit derived from a monomer having a hydroxyl group. (In general formula (1): R1, R2 and R3 are each selected from a hydrogen atom and a methyl group; X1 represents an oxygen atom, an ester group, an amide group or -CH2O-; Y1 represents a repeating unit of an alkylene glycol having 2-4 carbon atoms; R4 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; and n represents the number of repeating units of the alkylene glycol.)SELECTED DRAWING: None 【課題】油中分散体のスラリー粘度を低減することで塗布性及び成形性を向上することができ、及びハロゲン系樹脂組成物加工性を向上し、耐低温屈曲性を向上することのできる高分子分散剤を提供する。【解決手段】下記一般式(1)で表されるモノマー由来の構成単位と、水酸基を有するモノマー由来の構成単位とを含む非水系溶剤用の高分子分散剤に関する。JPEG2024079606000032.jpg2559(一般式(1)中、R1、R2、及びR3は、それぞれ、水素元素及びメチル基から選択され、X1は、酸素元素、エステル基、アミド基、又は-CH2O-を表し、Y1は、炭素数2~4のアルキレングリコールの繰り返し単位を表し、R4は、水素元素又は炭素数1~20のアルキル基を表す。nは、前記アルキレングリコールの繰り返し単位数を表す。)【選択図】なし
