PROBLEM TO BE SOLVED: To provide a compatibility accelerator capable of finely dividing a phase separation structure in a dynamic crosslinking body of a thermoplastic resin and a rubber.SOLUTION: The compatibility accelerator is a compatibility accelerator used when a butyl rubber is crosslinked dynamically in the presence of a thermoplastic resin having at least one functional group selected from an ester group, an amide group and a hydroxyl group in a repeating unit, the compatibility accelerator having a polyisobutylene skeleton and having, in at least one end, a functional group capable of hydrogen bonding to the functional group of the thermoplastic resin (for example, an amino group, an ureido group, a carboxyl group, a hydroxyl group and a mercapto group).SELECTED DRAWING: None
【課題】熱可塑性樹脂とゴムとの動的架橋体における相分離構造を細かくすることができる相溶化剤を提供する。【解決手段】実施形態に係る相溶化剤は、エステル基、アミド基、及びヒドロキシル基からなる群から選択される少なくとも1種の官能基を繰り返し単位に有する熱可塑性樹脂の存在下で、ブチルゴムを動的に架橋させる際に用いられる相溶化剤であって、ポリイソブチレン骨格を持ち、少なくとも1つの末端に前記熱可塑性樹脂の官能基と水素結合可能な官能基(例えば、アミノ基、ウレイド基、カルボキシル基、ヒドロキシル基、及びメルカプト基など)を有するものである。【選択図】なし
