摘要： A pressureless pipe and polymer composition for making such a pipe as well as the use of the polymer composition for pressureless pipes and supplementary parts, are disclosed. The polymer composition is characterised in that the polymer comprises a multimodal ethylene polymer including a copolymer of ethylene and a C4-C10 alpha -olefin comonomer; the ethylene polymer has a total density of at least 950 kg/m and a MFR5 of 0.2-2.0 g/10 min; the ethylene polymer has a modulus of elasticity, determined according to ISO 178 of more than 1200 MPa; the ethylene polymer has a resistance to slow crack growth, determined according to ASTM F 1473 of more than 1.5 hrs.
