Title (EN) OLEFIN-BASED POLYMERS AND DISPERSION POLYMERIZATIONS
(FR) POLYMÈRES OLÉFINIQUES ET POLYMÉRISATIONS EN DISPERSION
Abstract:
(EN) The invention provides a polymerization process comprising polymerizing a reaction mixture comprising one or more monomer types, at least one catalyst, and at least one solvent, to form a polymer dispersion, and wherein the at least one catalyst is soluble in the at least one solvent, and wherein the polymer forms a dispersed phase in the solvent, and wherein the at least one solvent is a hydrocarbon. The invention provides a composition comprising an ethylene-based polymer comprising at least the following properties: a) a weight average molecular weight (Mw(abs)) greater than, or equal to, 60,000 g/mole; and b) a molecular weight distribution (Mw(abs)/Mn(abs)) greater than, or equal to, 2.3.
(FR) Cette invention concerne un processus de polymérisation consistant à polymériser un mélange réactionnel comprenant un ou plusieurs types de monomères, au moins un catalyseur et au moins un solvant de manière à former une dispersion polymère, ledit catalyseur étant soluble dans ledit solvant, ledit polymère formant une phase dispersée dans le solvant, ledit solvant étant un hydrocarbure. L'invention concerne une composition comprenant un polymère éthylénique doté des propriétés suivantes : a) masse moléculaire moyenne en poids (Mw(abs)) supérieure ou égale à 60 000 g/mole ; et b) répartition des masses moléculaires (Mw(abs)/Mn(abs)) supérieure ou égale à 2,3.
