Abstract
Procedimiento para la elaboracion de homo- y copolímeros de etileno con un rango de densidad de hasta 0,930 g/cm3 y un rango de índice de fusion entre0,15 y 25 g/10 min (2,16 kg; 463 sK), con una mejor estabilidad operativa y disponibilidad deequipo s, con presiones superiores a 1000 bar y a temperaturas dehasta 603 sK en reactores tubulares, en presencia de iniciadores formadores de radicales, entre ellos, oxígeno y reguladores de cadena, de los cuales a lomenos uno presenta unaestructura alde hídica. En tal procedimiento se acoplan datos de cinética química de los materiales reactivos empleados (períodos de vidamedia térmica, concentraciones, cantidades a dosificar) con datos relevantes de la mecánica de fluidos delreactor tubular (veloc idad de circulacion ),tomando en consideracion la calidad deseada del producto (índice de fusion, índice de fluencia), de modo de reducir a un mínimo las reacciones secundariasperturbadoras, en particular, los efectos desustitucion polar inductivos que puedan conducir a un enriquecimiento en hidroperoxidos orgánicos y, con ello,poder lograr condiciones de proceso extraordinariamente estables.
