Реферат: EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA PRODUCIR POLIMERIZADOS DE ETILENO ULTRAMOLECULARES EN FASE GASEOSA Y EN UN LECHO A GRANEL MEZCLADO DE POLIMERIZADO FINAMENTE DIVIDIDO QUE CONSISTE EN LA INTRODUCCION CONTINUA DE LOS MONOMEROS CORRESPONDIENTES EN UN SISTEMA DE POLIMERIZACION, ENTRE 60 Y 120 C Y A UNA PRESION DE 5 A 10 MBAR Y EN PRESENCIA DE CATALIZADORES CONTENIENDO TITANIO Y ANTIESTATICAS Y DESCRIBE UN POLIMERIZADO DE ETILENO ULTRAMOLECULAR PRODUCIDO SEGUN EL PROCEDIMIENTO. THE INVENTION IS RELATED TO A PROCEDURE FOR PRODUCING ULTRAMOLECULAR ETHYLENE POLYMERIZES IN A GASEOUS PHASE AND IN A FINALLY DIVIDED MIXED BULK PLANT CONSISTING OF A CONTINUOUS INTRODUCTION OF 60 YEARS AND A CORRESPONDING POLYERISE IN A SISTRE FROM 5 TO 10 MBAR AND IN THE PRESENCE OF CATALYSTS CONTAINING TITANIUM AND ANTI-STATICS AND DESCRIBES AN ULTRAMOLECULAR ETHYLENE POLYMERIZED PRODUCED ACCORDING TO THE PROCEDURE.
