Title (EN) THERMOPLASTIC OLEFIN COMPOSITIONS
(FR) COMPOSITIONS OLÉFINIQUES THERMOPLASTIQUES
Abstract:
(EN) An in-reactor polymer blend comprises (a) a propylene-containing first polymer; and (b) propylene-containing second polymer having a different crystallinity from the first polymer. The polymer blend has a melting temperature, Tm, of at least 135 °C, a melt flow rate of at least 70 dg/min, a tensile strength of at least 8 MPa, an elongation at break of at least 300%.
(FR) La présente invention concerne un mélange polymère en réacteur qui comprend (a) un premier polymère contenant du propylène; et (b) un second polymère contenant du propylène ayant une cristallinité différente du premier polymère. Le mélange polymère a une température de fusion, Tm, d'au moins 135°C, un indice de fluidité d'au moins 70 dg/minute, une résistance à la traction d'au moins 8 MPa, une élongation à la rupture d'au moins 300 %.
