Abstract: The present invention is directed to a process for producing a modified olefin polymer having increased melt strength in an extruder. The process comprising the steps of: (A) contacting a stream comprising particles of an olefin polymer with a vapour stream of a functionally unsaturated compound in vapour phase thereby producing a first mixed stream; (B) passing the first mixed stream to an extruder; (C) melting the polymer particles of the first mixed stream in the extruder; (D) introducing a stream of a free radical generator either into the first mixed stream or into the extruder; and (E) extruding the first mixed stream and the free radical generator at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder.

Abstract: The present invention relates to a multimodal polyethylene composition which can be manufactured into pipes showing improved pressure resistance comprising a high density multimodal ethylene polymer component (A) having a density of at least 930 kg/m3, and a MFR21 of not more than 15 g/10 min, wherein said composition exhibits a LAOS-NLF defined as L ⁢ ⁢ A ⁢ ⁢ O ⁢ ⁢ S - N ⁢ ⁢ L ⁢ ⁢ F =  G 1 ′ G 3 ′  where G1′—first order Fourier Coefficient G3′—third order Fourier Coefficient of at least 1.7. Such a polyethylene composition is useful for the manufacture of pressure pipes that exhibit improved pressure resistance and creep resistance and do not undergo sagging. Further disclosed is a process for the production of a pipe using such a multimodal polyethylene composition and a pipe comprising such a multimodal polyethylene composition.
