Abstract: The present invention relates to an article coated with a composition comprising (A) an ethylene homo- or copolymer resin which has been prepared by using a single-site catalyst further characterized in that component (A) has an MFR21, measured according to ISO 1133 at 190° C. and under a load of 21.6 kg, from 0.01 to 20 g/10 min. The present invention further relates to an article coated with a composition comprising (A) an ethylene homo- or copolymer resin which has been prepared by using a single-site catalyst further characterized in that component (A) has an impact strength at ?40° C. of at least 80 kJ/m2 in a Charpy notched test according to ISO ISO 179-1/1eA:2000 with a pendulum energy of 15 J. The invention is furthermore directed to the use of the composition for the coating of an article.

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.

Abstract: The present invention relates to a process for manufacturing polyethylene-silane-copolymer conducted in a plant including at least one compressor unit and at least one reactor downstream of the compressor unit. The process includes the steps of (a) feeding a first feed stream including ethylene into the at least one compressor unit and subsequently to the at least one reactor, and (b1) feeding a second feed stream including at least one silane comonomer to the at least one reactor as front feed and/or (b2) feeding a second feed stream including at least one silane comonomer to the at least one reactor at at least one location along the reactor.
