Abstract

High mol., low pres., low density co- and ter-polymers are prepd. by polymsn. in liquid phase in presence of TiCl3/organo-Al cpd. catalyst in solvent mixt. comprising (a) propylene and/or butene-1, (b) butane and/or propane and (c) butene-2. Prods. have density 0.90-0.955 and mol. wt. 30,000 - 5,000,000.
