Abstract

Un artículo de espuma polimérica extruida que comprende una matriz polimérica con una fase polimérica termoplástica continua, definiendo la matriz polimérica una multitud de celdas en la misma y teniendo la fase polimérica termoplástica continua una fase continua de polímero de estireno-acrilonitrilo caracterizada por tener: a. un contenido de acrilonitrilo de 20 por ciento en peso o menos y cinco por ciento en peso o más, con el tanto por ciento en peso basado en el peso total del copolímero de estireno-acrilonitrilo; b. un contenido de comonómero de acrilonitrilo medio que excede su mediana de contenido de comonómero de acrilonitrilo; y c. una distribución de comonómero de acrilonitrilo copolimerizado media que tiene una amplitud a media altura que es mayor que 2,5 por ciento en peso, medida a media altura de pico de una curva de distribución de comonómero de acrilonitrilo copolimerizado para el copolímero de estireno-acrilonitrilo.
