Title (EN) POLYETHYLENE COMPOSITION FOR WATER PIPES WITH IMPROVED CHLORINE RESISTANCE
(FR) COMPOSITION DE POLYÉTHYLÈNE POUR CANALISATIONS D'EAU AYANT UNE RÉSISTANCE ACCRUE AU CHLORE
Abstract:
(EN) The present invention is directed to the use of compound (A) and compound (B) in a polyethylene composition for increasing the lifetime of a pipe made of said polyethylene composition which is in permanent contact with chlorinated water, wherein compound (A) has the following formula (I): wherein - R6, R7 and R8 independently are non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise OH-groups, X1, X2, and X3 independently are H or OH, with the proviso that at least one of X1, X2, and X3 is OH, and the entire molecule does not comprise an ester group; wherein compound (B) has the following formula (II): wherein R1, R2, R3, R4 and R5 independently are H, or non-substituted or substituted aliphatic or aromatic hydrocarbyl radicals which may comprise heteroatoms, and wherein the base resin of said polyethylene composition consists of a polyethylene homo-or copolymer.
(FR) La présente invention porte sur l'utilisation d'un composé (A) et d'un composé (B) dans une composition de polyéthylène pour l'augmentation de la durée de vie d'une canalisation constituée de ladite composition de polyéthylène qui est en contact permanent avec de l'eau chlorée, le composé (A) ayant la formule suivante (I) : dans laquelle R6, R7 et R8 représentent indépendamment des radicaux hydrocarbyles aliphatiques ou aromatiques non substitués ou substitués qui peuvent comprendre des groupes OH, X1, X2, et X3 représentent indépendamment H ou OH, à la condition qu'au moins l'un parmi X1, X2, et X3 soit OH et que la molécule entière ne comprenne pas un groupe ester; le composé (B) ayant la formule suivante (II) : dans laquelle R1, R2, R3, R4 et R5 représentent indépendamment H ou des radicaux hydrocarbyles aliphatiques ou aromatiques non substitués ou substitués qui peuvent comprendre des hétéroatomes, et la résine de base de ladite composition de polyéthylène étant constituée d'un homopolymère ou copolymère de polyéthylène.
