Abstract

Process for preparing chemically reducing solid bodies, characterized in that it comprises polymerizing an olefin of the formula ACH = CH2, in which A is hydrogen or an aliphatic radical containing 1 to 8 carbon atoms, in contact on the one hand with solid particles consisting of a compound of a transition metal of sub-groups IVa, Va and VIa of the periodic classification of the elements and, on the other hand, with an organomagnetic compound.
