A solid catalyst component contg. Mg, Ti and halogen for use in the polymerisation of alpha-olefins is prepd. by (a) contacting a cpd. of formula MgR'R''xCO2 (I) in which R' is alkoxy or aryloxy gp., R'' is halogen, alkoxy or aryloxy and x is 0.1-2.0, with a Ti (IV) halide in the presence of a halohydrocarbon and an electron donor; (b) contacting the halogenated prod. with a Ti (IV) halide; (c) washing the prod. to remove unreacted Ti cpds. and (d) recovering the solid prod.
