Abstract
NUEVOS HOMOPOLIMERIZADOS Y COPOLIMERIZADOS DE ETILENO ADECUADOS PARA LA PRODUCCION DE LAMINAS, CON UNA DENSIDAD DE 925 A 940 KG/M3, UN INDICE DE CORRIENTE DE FUSION (MELT-FLOW-INDEX, MFI) A 190 (GRADOS) C Y UNA FUERZA DE APOYO DE 2,16 KP < 1 G/10 MIN, SON OBTENIBLES POR LA POLIMERIZACION RADICAL DE LOS MONOMEROS A UNA PRESION DE 500 A 5000 BAR Y A UNA TEMPERATURA DE REACCION T DE 40 A 320 (GRADOS) C, POR MEDIO DE UN INICIADOR, BAJO EXCLUSION PRACTICA DE OXIGENO, EN AL MENOS N = 3 FASES DE POLIMERIZACION. ASI SE SOMETE EN LA PRIMERA FASE AL CONJUNTO O LA PARTE PREDOMINANTE DE LOS MONOMEROS, POR MEDIO DE UNA PARTE DE LOS INICIADORES NECESARIOS, A LA POLIMERIZACION DURANTE TANTO TIEMPO HASTA QUE ESTE LLEGUE PRACTICAMENTE AL REPOSO. ENTONCES SE ADICIONA A LA MEZCLA ENFRIADA A 20 A 60 (GRADOS) C, UNA PARTE ADICIONAL DEL INICIADOR, Y DADO EL CASO DEL MONOMERO. ESTE PROCEDIMIENTO SE REPITE EN LAS FASES SIGUIENTES HASTA LA FASE N, POR LO QUE AL MENOS EL INICIADOR UTILIZADO EN LA FASE N PRESENTA UNATEMPERATURA MEDIA DE 90 A 260 (GRADOS) C, Y LA TEMPERATURA DE REACCION MAXIMA, TMAX SE ENCUENTRA AL MENOS EN LA FASE N, CERCANA O POR ENCIMA DE 270 (GRADOS) C.
