Propylene is polymerized by use of a catalyst prepared by grinding an Al/TiCl3 mixture in an initial weight ratio of 1 : 2-100 : 1 in presence of hydrogen until substantially 1 atom of H has been absorbed for each two atoms of Al present. The polymerization reaction is preferably effected in an inert liquid hydrocarbon.ALSO:Propylene is polymerized by use of a catalyst prepared by grinding an Al/TiCl3 mixture in an initial weight ratio of 1:2-100:1 in presence of hydrogen until substantially 1 atom of H has been absorbed for each two atoms of Al present.
