ABSTRACT OF THE DISCLOSURE An ethylene polymer having a density in the range Or about 0.940-0.960, a melt index in the range 100-200 and a ratio of weight-average molecular weight to number-average molecular weight of less than 5 is disclosed. The polymer is a copolymer of ethylene and at least one .alpha.-olefin having 4-10 carbon atoms e.g. butene-1, hexene-1 or octene-1. The preferred polymer is a copolymer of ethylene and butene-1. The polymers may be used in the injection moulding of thin- wall containers e.g. containers having a wall thickness of less than 0.7 mm, especially a thickness of less than 0.5 and in particular a thickness of less than 0.4 mm.
