Title
(EN) SILANE-COUPLED PROPYLENE-BASED POLYMER AND METHOD
(FR) POLYMÈRE À BASE DE PROPYLÈNE COUPLÉ PAR SILANE ET PROCÉDÉ CORRESPONDANT
Abstract
(EN)
The present disclosure provides propylene-based polymers which exhibit a strain hardening distribution factor that is less than zero and/or a strain hardening factor greater than 1.5. The propylene-based polymers are rheology-modified by way of silane coupling to improve melt strength.
(FR)
La présente invention porte sur des polymères à base de propylène qui présentent un facteur de distribution du rhéodurcissement qui est inférieur à zéro et/ou un facteur de rhéodurcissement supérieur à 1,5. Les polymères à base de propylène sont rhéomodifiés au moyen d'un couplage de type silane pour améliorer la résistance à l'état fondu.
