Beschreibung
Zusammenfassung:	This addition type polymer is added to a silicone hydrogel to improve tensile break strength and toughness of the silicone hydrogel and contains a benzotriazole skeleton without containing polymerizable groups. L'invention concerne un polymère d'addition ajouté à un silicone hydrogel pour améliorer la résistance à la rupture par traction et la ténacité du silicone hydrogel et contient un squelette benzotriazole sans contenir de groupes polymérisables. 添加型ポリマーは、シリコーンハイドロゲルに添加されシリコーンハイドロゲルの引張破壊強さ及び強靱性を向上させる添加型ポリマーであって、ベンゾトリアゾール骨格を含み重合基を有しないものである。
