Abstract
Mono-olefins such as ethylene, propylene and aryl olefins, are polymerized to linear products using a catalyst obtained from an organo-tin compound and a compound of a transition metal of Groups IV to VIII. The polymerization is preferably in an organic solvent such as kerosene or heptane, and may be effected with intermittent addition of monomer. Catalyst components specified are TiCl4, TiCl3, MoCl3/MoCl5, VCl4, SnR4 (e.g. SnEt4) and SnAr4 (e.g. Sn#f4). Catalyst residues may be removed by means of materials such as ether/HCl, water, acetone and methanol. In example 8 oily polypropylene is separated from solid polypropylene. Specifications 818,033 and 823,236 are referred to.ALSO:A catalyst for polymerizing olefines is obtained from an organo tin compound and a compound of a transition metal of Group IV to VIII.
