To provide a method for material-recycle a silane cross-linked polyethylene-containing polyethylene resin by using a simple apparatus and adding a highly safe additive to thermo-plasticize the resin in an effective manner.SOLUTION: A material-recyclable regenerated polymer can be obtained by applying shear stress to a polymer compound in which a cross-linked polyethylene resin and an additive selected from an aliphatic compound having 16 or more carbon atoms and having one or more hydroxyl groups and a boiling point of 300°C or more are mixed, to make it thermo-plasticized.SELECTED DRAWING: Figure 1 【課題】シラン架橋ポリエチレンを含むポリエチレン樹脂を簡便な装置を用い、かつ安全性が高い添加剤を加えて、効果的な方法で熱可塑化してマテリアルリサイクルする方法を提供する。【解決手段】架橋ポリエチレン樹脂と炭素数が１６以上であり、かつ１つ以上の水酸基を有する沸点が３００℃以上の脂肪族化合物から選択される添加剤を混合させた高分子化合物にせん断応力を加えて熱可塑化させることで、マテリアルリサイクルk可能な再生ポリマーを得ることができる。【選択図】図１
