Abstract: The present invention relates to a process for the manufacture of a saturated primary alcohol from an unsaturated aliphatic ester comprising the steps of: a) Providing an aliphatic ester having at least one carbon-carbon double bond; b) Carrying out a metathesis of said ester in the presence of a ruthenium carbene-based catalyst thereby obtaining a first reaction mixture; c) Adding a ligand and a base to the first reaction mixture, wherein the ligand comprises at least one donor atom chosen from the group consisting of a nitrogen atom and a phosphorus atom thereby obtaining a second reaction mixture comprising an ester product resulting from the metathesis reaction; d) Carrying out a homogeneous hydrogenation of the ester-product resulting from the metathesis, thereby obtaining a saturated primary alcohol. Further, the present invention relates to a catalyst for the hydrogenation of esters and to a process for the hydrogenation of esters using said catalyst.

Abstract: The invention relates to a process for the production of an article, wherein—ethylene is polymerized with a polyene and optionally another comonomer, resulting in a polymer with a MFI (21.6) between 0.05 dg/min and 100 dg/min,—melt processing the polymer into an article,—optionally crosslinking the polymer during or after melt processing the polymer and—optionally sterilizing the polymer article by high energy irradiation.
