ABSTRACT:
Solid catalytic complexes are useful for stereospecific polymerization of .alpha.-olefins to solid crystalline polymers. The complexes are formed by reducing TiCl.sub.4 with an alkylaluminum, treating thus-obtained reduced solid with a complexing agent and contacting the resultant with TiCl.sub.4. They have a specific surface greater than 75 m.sup.2 /g.
