Vinyl chloride polymerizations by Ti(OR) y Cl 4–y –AlR x Cl 3–x systems, using carbon tetrachloride as solvent, obey a radical mechanism. Free radicals are generated from alkyl aluminum by way of decomposition of an organometallic compound of tetravalent titanium; the latter is formed either by direct reaction between aluminum and titanium compounds, or after reoxidation by CCl 4 of a compound of trivalent titanium. The organometallic compound so obtained contains organic groups more complex than the alkyl group initially bond to aluminum.
