Patent ID: 7332543

Claim:
A rotomoulded article formed from a polymer composition comprising I) an ethylene homopolymer, having a melt flow rate of 0.5 to 30 g/10 min, a molecular weight distribution (Mw/Mn) of less than 4, an Mw of 50,000 to 110,000, a density of 0.940 g/cm 3 to 0.970 g/cm 3 and a melting point of 100 to 145° C.; and II) an ethylene copolymer with at least one other C 3-10 α-olefin, having a melt flow rate of within 40% of the melt flow rate of component (I), a molecular weight distribution of (Mw/Mn) of less than 4, an Mw of within 30% of the Mw of component (I), a density of 0.880 g/cm 3 to 0.940 g/cm 3 said density being at least 0.010 g/cm 3 less than the density of component (I) and a melting point of at least 5° C. less than that of component (I) wherein (I) and (II) are both formed by single site catalysts.
