## Abstract An investigation of ethylene‐propylene‐butene‐1 terpolymerization in the presence of TiCl~4~, Ti(OBu)~4~/MgCl~2~/ethylbenzoate (EB)/π~2~SiCl~2~/AlEt~3~ catalyst is described. The catalytic efficiency is very high, i.e., 86000g/g Ti under ambient conditions. The decay rate of terpolymeri
