POLYMER COMPOSITION FOR CONTAINER CLOSURES

The present invention relates to a polymer composition comprising an ethylene homopolymer and an ethylene copolymer having a comonomer content comprising a comonomer in an amount of at least 0.55 mol% with respect to the total amount of monomer in the ethylene copolymer, wherein the ethylene copolymer has a higher weight average molecular weight than the ethylene homopolymer, the polymer composition has a density in the range of 0.950-0.965 g/cm 3 , a melt flow rate (MFR 2 ) of at least 0.3 g/10 minutes, a weight average molecular weight of at least 100,000 g/mol, a and viscosity at an angular frequency of 0.01 [1/s], · 0.01 of at least 20,000 Pa.s wherein: the polymer composition has an Isothermal Crystallization Half-Time, ICHT which is less than 10 minute at 123 °C and a Full Notch Creep Test, FNCT of at least 60 hours.
