Title (EN) BUTENE-1 POLYMER COMPOSITION HAVING HIGH MELT FLOW RATE
(FR) COMPOSITION DE POLYMÈRE DE BUTÈNE-1 À INDICE DE FLUIDITÉ ÉLEVÉ
Abstract:
(EN) A butene-1 polymer composition having MFR values 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, comprising: A) a butene-1 homopolymer or a copolymer of butene-1 with one or more comonomers selected from ethylene and higher alpha-olefins, having a copolymerized comonomer content of up to 5% by mole; B) a copolymer of butene-1 with one or more comonomers selected from ethylene and higher alpha-olefins, having a copolymerized comonomer content of from 6% to 20% by mole; said composition having a total copolymerized comonomer content from 4% to 15% by mole, referred to the sum of A) and B), and a content of fraction soluble in xylene at 0°C of 75% by weight or less, determined on the total weight of A) and B).
(FR) L'invention concerne une composition de polymère de butène-1 qui présente des valeurs d'indice de fluidité (MFR) allant de 20 à moins de 100 g/10 min, mesurées selon la norme ISO 1133 à 190 °C avec une charge de 2,16 kg, et qui comprend : A) un homopolymère de butène-1 ou un copolymère de butène-1 avec au moins un comonomère choisi parmi l'éthylène et des alpha-oléfines supérieures, ayant une teneur en comonomère(s) copolymérisé(s) allant jusqu'à 5 % par mole ; B) un copolymère de butène-1 avec au moins un comonomère choisi parmi l'éthylène et des alpha-oléfines supérieures, ayant une teneur en comonomère(s) copolymérisé(s) de 6 % à 20 % par mole ; cette composition ayant une teneur totale en comonomère(s) copolymérisé(s) de 4 % à 15 % par mole, appelée somme de A) et B), et une teneur en fraction soluble dans le xylène à 0 °C de 75 % en poids ou moins, déterminée sur le poids total de A) et B).
