Abstract

SE PRESENTA UN POLIMERO DE ETILENO, SIN GEL, DE ELEVADO PESO MOLECULAR, NORMALMENTE SOLIDO QUE TIENE UNA DENSIDAD DE 0,89 A 0,97 G/CC QUE SE CARACTERIZA POR SU GRAN RESISTENCIA A LA FUSION DEBIDO AL ENDURECIMIENTO POR DEFORMACION QUE SE CREE ES LA CAUSA DE LAS RAMIFICACIONES DE LA CADENA LARGA DE EXTREMO LIBRE DE LAS CADENAS MOLECULARES QUE FORMAN EL POLIMERO. TAMBIEN SE PRESENTA UN PROCESO PARA LA FABRICACION DEL POLIMERO A BASE DE UNA RADIACION DE GRAN ENERGIA DE UN POLIMERO DE ETILENO DE ELEVADO PESO MOLECULAR, NORMALMENTE SOLIDO EN UN ENTORNO DE OXIGENO ACTIVO REDUCIDO, DE MANTENER EL MATERIAL IRRADIADO EN TAL ENTORNO DURANTE UN PERIODO DE TIEMPO ESPECIFICO Y DE DESACTIVAR DESPUES LOS RADICALES LIBRES DEL MATERIAL.
