MgCl 2 for use as a catalyst support was prepared by dissolution in methanol and recrystallization in n-decane, followed by vacuum-drying at 2,000 rpm. The prepared support was modified by treatment with alkylaluminum compounds. The activity profile of ethylene over the supported catalysts persisted
## Abstract Ring‐opening polymerization of 2‐phenyl‐1,3,2‐dioxaphosphorinane (a six‐membered cyclic phosphonite, 4) has been initiated with a new catalyst system of a halobenzene and NiBr~2~. The polymerization proceeded in a living nature to produce poly(phosphinate) consisting exclusively of a “n
