Title (EN) POLYMER PROCESSING
(FR) TRAITEMENT DE POLYMERES
Abstract: front page image
(EN)Oriented thermoplastics having enhanced properties such as Young's modulus, resistance to creep, resistance to gas transport are prepared by drawing the thermoplastic in the solid phase through a die so that its plastic strain is progressively increased during start-up.
(FR)Des plastiques thermodurcissables orientes ayant des proprietes ameliorees telles que le module d'Young, la resistance au fluage, la resistance au transport gazeux, sont prepares par etirage du materiau plastique dans la phase solide au travers d'une matrice de sorte que sa deformation plastique augmente progressivement pendant la mise en marche.
