Title (EN) LIQUID AND GEL-LIKE LOW MOLECULAR WEIGHT ETHYLENE POLYMERS
(FR) POLYMERES D'EYTHYLENE A FAIBLE POIDS MOLECULAIRE DE TYPE LIQUIDE ET GEL
Abstract:
(EN) The subject invention pertains to homogeneous liquid low molecular weight ethylene/alpha-olefin polymers having a number average molecular weight (Mn) as determined by gel permeation chromatography, of less than 25, 000, a total crystallinity, as measured by DSC, of less than 10 %, and a pour point, as measured by ASTM D97, of less than 50°C. The subject invention also pertains to homogeneous gel-like low molecular weight ethylene/alpha-olefin polymers having a number average molecular weight (Mn) as determined by gel permeation chromatography, of less than 25, 000, a total crystallinity, as measured by DSC, of less than 50%, and a pour point, as measured by ASTM D97, of less than 90°C.
(FR) L'invention porte sur des polymères d'éthylène/alpha-oléfiniques de faible poids moléculaire, liquides, homogènes, ayant un poids moléculaire moyen au nombre (Mn) tel que défini par la chromatographie par perméation sur gel, inférieur à 25 000, une cristallinité totale, telle que mesurée par DSC, inférieure à 10 % et un point de figeage, tel que mesuré par ASTM D97, inférieur à 50 °C. L'invention porte également sur des polymères d'éthylène/alpha-oléfiniques de faible poids moléculaire de type gel, homogènes, ayant un poids moléculaire moyen au nombre (Mn) tel que défini par la chromatographie per perméation sur gel, inférieur à 25 000, une cristallinité totale, telle que mesurée par DSC, inférieure à 50 % et un point de figeage, tel que mesuré par ASTM D97, inférieure à 90 °C.
