Abstract
SE DESCRIBE UNA CLASE DE POLIMEROS DE ETILENO DE ALTA DENSIDAD Y CON UN PESO MOLECULAR RELATIVAMENTE ALTO (PEDA-PMA) CAPAZ DE FORMAR PELICULAS FINAS DE GRAN RESISTENCIA, TENIENDO TALES POLIMEROS UNA DENSIDAD DE, AL MENOS, 0,935 GR/CC, APROXIMADAMENTE, UN INDICE DE FLUJO (L21) NO SUPERIOR A 15 GR/10 MIN., APROXIMADAMENTE, UNA MAGNITUD DE FLUJO DE FUSION (MFF) DE, AL MENOS, 65, APROXIMADAMENTE, Y UNA ELASTICIDAD DINAMICA DE 0,1 RAD./SEG. NO SUPERIOR A 0,7, APROXIMADAMENTE, A UNA VISCOSIDAD COMPLEJA CORRESPONDIENTE DE 0,1 RAD./SEG. NO SUPERIOR A 14E5, ES DECIR, DE 14 X 105 POISES, APROXIMADAMENTE. TALES POLIMEROS SE PRODUCEN MEDIANTE EL USO DE DOS REACTORES DE FASE GASEOSA EN SERIE. EN EL PRIMER REACTOR SE PRODUCE UN POLIMERO DE PMA CON UNA DENSIDAD DE, AL MENOS, 0,910 GR/CC, MIENTRAS QUE EN EL SEGUNDO REACTOR SE PRODUCE UN POLIMERO DE PMB CON UNA DENSIDAD DE, AL MENOS, 0,940 GR/CC.
