Title (EN) ELASTOMERIC REACTOR BLEND COMPOSITIONS
(FR) COMPOSITIONS ELASTOMERES ISSUES DE MELANGE DE REACTEUR
Abstract:
(EN) Disclosed herein are various processes, including but not limited to a continuous process for making an elastomer composition having a Mooney Viscosity (ML (1+4) @ 125 °C) of from 16 to 180, the composition including a first polymer and a second polymer, the process comprising: polymerizing a first monomer system that includes propylene and one or both of ethylene and propylene in a solvent using a first catalyst system in a first polymerization zone to provide a first polymer, having 60 wt% or more units derived from propylene, including isotactically-arranged propylene-derived sequences and further having a heat of fusion less than 45 J/g or a melting point less than 105 °C or both and a Mooney Viscosity (ML (1+4) @ 125 °C) of from I to 45; polymerizing a second monomer system that includes ethylene or an alpha-olefin, or both, in a solvent using a second catalyst system in a second polymerization zone to provide a second polymer which is an elastomeric polymer that is either non-crystalline or has ethylene-derived crystallinity; combining the first polymer and the second polymer in a mixture that includes solvent and unreacted monomer; and removing solvent from the mixture to provide an elastomer composition that having a Mooney Viscosity (ML (1+4) @ 125 °C) of from 16 to 180.
(FR) L’invention décrit plusieurs procédés, y compris mais sans s’y limiter, un procédé continu pour réaliser une composition élastomère ayant une consistance Mooney (ML (1+4) à 125 °C) allant de 16 à 180, la composition comprenant un premier polymère et un deuxième polymère, lequel procédé comprend : la polymérisation d’un premier système de monomères qui inclut du propylène et un ou les deux composés parmi l’éthylène et le propylène, dans un solvant utilisant un premier système catalyseur dans une première zone de polymérisation afin de fournir un premier polymère, ayant 60 % en poids ou davantage de motifs dérivés du propylène, y compris des séquences dérivées du propylène arrangées de manière isotactique et ayant en outre une chaleur de fusion inférieure à 45 J/g ou un point de fusion inférieur à 105 °C, ou les deux, et une consistance Mooney (ML (1+4) à 125 °C) allant de 1 à 45 ; la polymérisation d’un deuxième système de monomères qui inclut de l’éthylène ou une alpha-oléfine, ou les deux, dans un solvant utilisant un deuxième système catalyseur dans une deuxième zone de polymérisation afin de fournir un deuxième polymère qui est un polymère élastomère non cristallin qui a une cristallinité dérivée de l’éthylène ; la combinaison du premier et du deuxième polymères dans un mélange qui inclut le solvant et les monomères n’ayant pas réagi ; enfin, l’élimination du solvant du mélange afin de fournir une composition élastomère ayant une consistance Mooney (ML (1+4)à 125 °C) de 16 à 180.
