Title (EN) BUTENE-1 POLYMER HAVING A HIGH MELT FLOW RATE
(FR) POLYMÈRE DE BUTÈNE-1 À INDICE DE FLUIDITÉ ÉLEVÉ
Abstract:
(EN) A butene-1 polymer having: a) a Melt Flow Rate value of from 20 to less than 100 g/10 min., measured according to ISO 1133 at 190°C with a load of 2.16 kg; • b) an intrinsic viscosity (IV) measured in tetrahydronaphthalene (THN) at 135°C equal to lower than 0.95 dl/g; • c) a Mw/Mn value equal to or lower than 3.5, the lower limit being of 1.5; • d) a Mz value of 180,000 g/mol or higher; • e) a comonomer content, when comonomer is present, of up to 5% by weight.
(FR) L'invention concerne un polymère de butène-1 ayant : • a) une valeur d'indice de fluidité de 20 à moins de 100 g/10 min, mesurée selon la norme ISO 1133 à 190 °C avec une charge de 2,16 kg ; • b) une viscosité intrinsèque (IV) mesurée dans du tétrahydronaphtalène (THN) à 135 °C égale ou inférieure à 0,95 dl/g ; • c) une valeur Mw/Mn égale ou inférieure à 3,5, la limite inférieure étant de 1,5 ; • d) une valeur Mz de 180 000 g/mol ou plus ; • e) une teneur en comonomère, lorsqu'un comonomère est présent, allant jusqu'à 5 % en poids.
