Title
(EN) POLYETHYLENE FOR USE IN THE PRODUCTION OF CROSSLINKED POLYETHYLENE (PEX)
(FR) POLYÉTHYLÈNE DESTINÉ À ÊTRE UTILISÉ DANS LA PRODUCTION DE POLYÉTHYLÈNE RÉTICULÉ (PER)
Abstract
(EN) A polyethylene (PE) for the production of crosslinked polyethylene (PEX), having a beneficial balance of unsaturation properties and processability properties, processes for producing crosslinked polyethylene (PEX) from said polyethylene (PE), and the crosslinked polyethylene (PEX) thus produced.
(FR) L'invention concerne un polyéthylène (PE) pour la production de polyéthylène réticulé (PER), présentant un équilibre bénéfique entre propriétés d'insaturation et propriétés d'aptitude au traitement, des procédés de production de polyéthylène réticulé (PER) à partir dudit polyéthylène (PE) et le polyéthylène réticulé (PER) ainsi produit.
