To provide a polymer crosslinking agent which is capable of improving affinity for ester oil.SOLUTION: The polymer crosslinking agent is a (meth)acrylic-based graft silicone which comprises (meth)acryl-based repeating units represented by the following formulae (I), (II) and (III) as a main chain, and an unsaturated bond(s) and an organopolysiloxane structure at side chains. Also, the high molecular weight polymer is an addition polymerization product of the polymer crosslinking agent and an organohydrogen polymer, and a composition is a material in which the high molecular weight polymer is swollen by a liquid oil agent.SELECTED DRAWING: None 【課題】エステル油への親和性を向上させることができる高分子架橋剤を提供する。【解決手段】高分子架橋剤が下記式（Ｉ）、（ＩＩ）及び（ＩＩＩ）で表される、（メタ）アクリル系の繰り返し単位を有する主鎖と、不飽和結合およびオルガノポリシロキサン構造を側鎖に有する（メタ）アクリル系グラフトシリコーンである。また、高分子重合体はこの高分子架橋剤とオルガノハイドロジェンポリマーの付加重合物であり、組成物はこの高分子重合体が液状油剤により膨潤されているものである。【化１】【選択図】なし
