Title (EN) PROCESS FOR REDUCING THE WEIGHT AVERAGE MOLECULAR WEIGHT AND MELT INDEX RATIO OF POLYETHYLENES AND POLYETHYLENE PRODUCTS
(FR) PROCEDE DESTINE A REDUIRE LE POIDS MOLECULAIRE MOYEN EN POIDS ET LE RAPPORT D'INDICE DE FUSION DES POLYETHYLENES ET DES PRODUITS DE POLYETHYLENE
Abstract:
(EN) There is described a process for producing ethylene homopolymers and/or interpolymers and functionalized ethylene homopolymers and/or interpolymers, having reduced melt index ratio (MIR) and reduced weight average molecular weight (Mw). Also disclosed are novel ethylene homopolymers and interpolymers and functionalized ethylene homopolymers and/or interpolymers, having melt index ratio (MIR) less than 22 and molecular weight distribution greater than 2.4. Further described are novel ethylene interpolymers and functionalized ethylene interpolymers, having a melt index ratio less than 26, a molecular weight distribution value of greater than 2.4 and a density of less than 0.95 g/cc.
(FR) L'invention concerne un procédé de production d'homopolymères et/ou d'interpolymères d'éthylène et d'homopolymères et/ou d'interpolymères d'éthylène fonctionnels présentant un rapport d'indice de fusion réduit ainsi qu'un poids moléculaire moyen en poids (Mw) réduit. L'invention concerne également de nouveaux homopolymères et interpolymères d'éthylène et de nouveaux homopolymères et/ou interpolymères d'éthylène fonctionnels présentant un rapport d'indice de fusion inférieur à 22 et une distribution de poids moléculaire supérieure à 2,4. L'invention concerne enfin de nouveaux interpolymères d'éthylène et interpolymères d'éthylène fonctionnels présentant un rapport d'indice de fusion inférieur à 26, une valeur de distribution de poids moléculaire supérieure à 2,4 et une densité inférieure à 0,95 g/cc.
