Abstract

Un método puede incluir reprocesar una composición polimérica que comprende una composición polimérica reticulada, donde la composición polimérica reticulada comprende un polímero de matriz que tiene una fase interna del polímero polar que se retícula selectivamente con un agente de reticulación, donde la composición polimérica reprocesada retiene una resistencia al agrietamiento por estrés ambiental dentro de 60% del valor para la composición polimérica inicial cuando se mide de acuerdo con ASTM D-1693 procedimiento B y donde la composición polimérica reprocesada presenta un Índice de equilibrio de propiedades normalizado (NPBI) mayor de aproximadamente 1,0.One method may include reprocessing a polymer composition comprising a cross-linked polymer composition, where the cross-linked polymer composition comprises a matrix polymer having an internal phase of the polar polymer that selectively cross-links with a cross-linking agent, where the reprocessed polymer composition retains a resistance to environmental stress cracking within 60% of the value for the initial polymer composition when measured in accordance with ASTM D-1693 procedure B and where the reprocessed polymer composition exhibits a Normalized Property Balance Index (NPBI) greater than approximately 1 , 0.
