Title (EN) AMORPHOUS PROPYLENE-ETHYLENE COPOLYMERS
(FR) COPOLYMÈRES AMORPHES DE PROPYLÈNE-ÉTHYLÈNE
Abstract:
(EN) Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.
(FR) L’invention concerne des copolymères amorphes de propylène-éthylène qui peuvent contenir des quantités élevées d'éthylène et présenter des points de ramollissement et des pénétrations d'aiguille souhaitables. Les combinaisons souhaitables de points de ramollissement et pénétrations d'aiguille dans ces copolymères de propylène-éthylène leur permettent de bénéficier d'une large fenêtre de mise en œuvre. Grâce à leur large fenêtre de mise en œuvre, les copolymères de propylène-éthylène selon l'invention peuvent être utilisés dans une large gamme d'applications et de produits, comprenant les adhésifs thermofusibles.
