Abstract

Se describe un artículo moldeado por soplado que comprende un interpolímero de etileno / a-olefina. El interpolímero de etileno / a-olefina tiene una densidad de 0,920 g/cc a 0,950 g/cc, un índice de fusión (I₂) de 0,5 g/10 minutos a 10,0 g/10 minutos, un índice de amplitud de distribución de comonómeros (CDBI) mayor que 55%. La a-olefina de etileno también tiene una CDFLS × LCBf × 100 mayor que 0,5 en donde la CDFLS y la LCBf se miden como se describe a continuación. También se describe un artículo moldeado por soplado que forma una botella mediante moldeo por soplado de un interpolímero de etileno / a-olefina que tiene una densidad de 0,920 g/cc a 0,950 g/cc, un índice de fusión (I₂) de 0,5 g/10 minutos a 10,0 g/10 minutos, un índice de amplitud de distribución de comonómero (CDBI) mayor que o igual a 55%, y un valor de CDFLS × LcBF × 100 mayor que 0,5, en donde la CDFLS se calcula midiendo una fracción de área de una distribución de peso molecular obtenida a partir de la distribución del peso molecular absoluto y la LCBf se mide como se describe a continuación.
