筆者らは, メタロセン触媒系において, 高性能で安価な活性化剤 (助触媒) を探索し, 粘土鉱物をメタロセン錯体と組み合わせると, きわめて高い活性が発現することを見いだした. また, 粘
Acid treated clay (montmorillonite) was reacted with AlEt3 (TEA) to give TEA-treated montmorillonite (TEA-Montmorillonite). Various amounts of 2,6-dimethylpyridine (26DMP) was added to TEA-Montmorillonite in order to control the acid strength of TEA-
