Patent ID: 7807770

Claim:
A drawn tape, fibre or filament comprising a multimodal polyethylene resin having: a density of at least 940 kg/m 3 , a melt index MI 5 of 0.05 to 5 g/10 min, a molecular weight distribution (M w /M n ) of less than 40, a relationship between dynamic viscosity η 0.01 , measured in Pa·s at 0.01 rad/s and 190° C., and dynamic viscosity η 100 , measured in Pa·s at 100 rad/s and 190° C., expressed by the equation η 100 <x. η 0.01 0.55 , where x=7.4, a melt storage modulus G′, measured at 190° C. and a dynamic frequency where the loss modulus G″=3000 Pa, of greater than 710 Pa, and a relationship between said melt storage modulus and the melt storage modulus at a dynamic frequency where the loss modulus G″=500 Pa, expressed by the equation G′(G″=3000)>300+5.5*G′(G″=500), wherein the tape, fibre or filament has been drawn to at least 4 times its original length.
