Abstract
Improvements introduced in the object of the main patent no. 436,796, granted on august 23, 1976 by: "process for polymerizing an alpha-olefin" under conditions characteristic of polymerization of ziegler, in which a catalyst is used as described in said main patent, characterized in that polymers of alpha-olefins having a high bulk density are prepared, using a catalyst prepared as in the main patent except that the concentration of the magnesium in the intermediate reaction mixture is greater than 0.1 molar.
