Abstract
Se proporcionan métodos para procesar reciclados de LLDPE incluyendo, a modo no taxativo, polietileno y polipropileno y composiciones a partir de los mismos. El reciclado de LLDPE puede tener viscosidad reducida para mejorar las características de procesamiento y/o desvolatilizarse para eliminar los subproductos de desecho para producir reciclados de LLDPE procesados. Los reciclados de LLDPE procesados se mezclan con poliolefinas de preconsumo para producir composiciones de mezcla que tienen características de procesamiento aceptables o incluso mejoradas. Estas poliolefinas de preconsumo también pueden someterse a una reducción de viscosidad para adaptar aún más las características de procesamiento de las mezclas de polímero. Puede usarse una combinación de extrusores y/o zonas de extrusión en la misma o en diferentes ubicaciones para la reducción de viscosidad y/o la composición tanto de reciclados de LLDPE como de poliolefinas de preconsumo.
