Title (EN) PROCESS FOR FORMING POLYMER BLENDS
(FR) PROCÉDÉ POUR FORMER DES MÉLANGES POLYMÈRES
Abstract:
(EN) A method for forming a polymer blend, the method comprising charging to a reactive extruder a first polymer and a second polymer to form an initial blend, where the first polymer is a propylene-based elastomer including up to 35% by weight ethylene-derived units and a heat of fusion, as determined according to DSC procedures according to ASTM E-793, of less than 80 J/g and a melt temperature of less than 110°C, where the second polymer is a propylene-based polymer having a melt temperature in excess of 110°C and a heat of fusion in excess of 80 J/g.
(FR) L’invention concerne un procédé pour former un mélange polymère, qui consiste à charger un premier et un second polymère dans une extrudeuse réactive pour former un mélange initial, le premier polymère étant un élastomère à base de propylène qui comprend jusqu’à 35% en poids d’unités dérivées d’éthylène, et présente une chaleur de fusion, telle que déterminée par les procédures DSC selon la norme ASTM E-793, inférieure à 80 J/g et une température de fusion inférieure à 110°C, et le second polymère étant un polymère à base de propylène dont la température de fusion est supérieure à 110°C et la chaleur de fusion supérieure à 80 J/g.
