Abstract
Un método de obtención de espumas de resinas poliméricas etilénicas blandas, con una estructura de celdillas esencialmente cerradas y espesores superiores a 0,5" (1,27 cm), a partir de resinas poliméricas etilénicas de partida de poca rigidez, inferior a 20.00 psi (1.400 kg/cm2), que comprenden copolímeros de etileno poco rígidos preparados mediante copolimerización de una mayor proporción de etileno con una menor proporción de comonómeros no iónicos copolimerizables.
