  • Publication number: 20220177680
    Abstract: The invention relates to the use of a polyethylene composition comprising one or more ethylene copolymer(s) wherein the ethylene copolymer is a terpolymer containing monomer units with polar groups and monomer units with hydrolysable silane groups, wherein the monomer units with polar groups are present in an amount of more than 5 mol. % based on the total polyethylene composition, and a silanol condensation catalyst in an amount of 0.0001 to 5 wt. %, based on the total polyethylene composition for improving the adhesion between a layer of a cable comprising the polyethylene composition and a polyurethane resin.

  • Publication number: 20190067704
    Abstract: The invention concerns a method for manufacturing of an electrocatalyst comprising a porous carbon support material, a catalytic material in the form of at least one type of metal, and macrocyclic compounds chemically bound to the carbon support and capable of forming complexes with single metal ions of said metal or metals, said method comprising the steps of: i) providing a template capable of acting as pore structure directing agent during formation of a highly porous electrically conducting templated carbon substrate, ii) mixing the template with one or several precursor substances of the catalytic material, the macrocyclic compounds and carbon, iii) exposing the mixture of the template and the precursor substances to a carbonization process during which the precursors react and transform the mixture into a carbonized template composite in winch the carbon part of the composite is chemically bound to macrocyclic compounds present in complexes with the metal or metals.

  • Patent number: 9255159
    Abstract: The present invention provides a process for manufacturing polyethylene-diene-copolymer conducted in a plant including at least one compressor unit, at least one preheater unit downstream of the compressor unit and at least one reactor, in particular a reactor, downstream of the compressor unit and the preheater unit. The process comprising the steps of (a) feeding a first feed stream comprising ethylene into the at least one compressor unit and subsequently into the at least one preheater unit, and (b1) feeding a second feed stream including at least one diene comonomer to the first feed stream leaving the at least preheater unit, and feeding the combined feed streams including ethylene and the at least one diene comonomer to the at least one reactor, and/or (b2) feeding a second feed stream including at least one diene comonomer to the at least one reactor at at least one location along the reactor.
