Abstract

A process for the copolymerization of butene-1 with propylene comprises polymerizing a mixture of propylene and butene-1 in the presence of a stereospecific catalyst, which is defined as one which will under equivalent conditions polymerize propylene in the absence of other monomers to polypropylene which is at least 70% insoluble in boiling heptane, and recovering a solid crystalline copolymer of propylene and butene-1 comprising 5 to 50% by wt. of randomly copolymerized propylene (defined). The stereospecific catalyst is preferably a trivalent titanium compound activated with an aluminium alkyl compound. Preferably the copolymer is obtained as a slurry by using a catalyst which has been heated by mutually polymerizing a 1-olefine, e.g. propylene, butene-1 or b -methylbutene-1 in the presence of the catalyst. The weight of polymer formed in this stage is preferably between 1 and 5% by wt. of the total polymer.
