[54] POLYETHYLENE FOR THE PRODUCTION OF TIGHT HEAD DRUMS
[57] Abstract: The invention is directed to a pelletized ethylene polymer having: ? a density > 954 kg/m3 and ? 959 kg/m3 ( according to ISO 1183)? a high-load melt index ? 1.7 g/10 min and ? 10 g/10 min (according to ISO 1133;190°C;21.6 kg))? an Izod impact strength (-30°C) ? 40 KJ/m2 and ? 90 KJ/m2 (according to ISO 180/A) and ? Mw / Mn ? 8 and ? 17 (according to size exclusion chromatography). The strain hardening modulus of the polymer ? 10 and ? 25 (according to the method as described in Elsevier, Polymer 46(2005) 6369-6379). The polyethylene is applied in the production of tight head drums.
