PROBLEM TO BE SOLVED: To provide a method for producing polybutylene ether di(meth) acrylate that has a reduced amount of waste acid, allows the reuse of catalysts, and makes it easy to control molecular weights.SOLUTION: The present invention relates to a method for producing polybutylene ether di(meth) acrylate by the ring opening polymerization of tetrahydrofuran in the presence of a solid acid catalyst and (meth)acrylic anhydride. The solid acid catalyst is preferably activated clay.SELECTED DRAWING: None 【課題】 廃酸量が少なく、触媒の再利用が可能であり、且つ、分子量の調節が容易であるポリブチレンエーテルジ（メタ）アクリレートの製造方法を提供する。【解決手段】 固体酸触媒及び無水(メタ)アクリル酸の存在下、テトラヒドロフランを開環重合させてポリブチレンエーテルジ（メタ）アクリレートを製造する方法：固体酸触媒は活性白土であることが好ましい。【選択図】 なし
