Abstract

PROCEDE DE PREPARATION D'UNE POLYOLEFINE EN UTILISANT UN CATALYSEUR DE ZIEGLER. DANS CE PROCEDE, UNE OLEFINE EST MISE EN CONTACT AVEC UN CATALYSEUR COMPRENANT UN CONSTITUANT CATALYTIQUE SOLIDE CONSTITUE D'UN HALOGENURE DE MAGNESIUM, D'UN COMPOSE HALOGENE DU TITANE ET D'UN COMPOSE DONNEUR D'ELECTRONS, DEPOSE SUR UN SUPPORT D'OXYDE METALLIQUE CONTENANT DE LA SILICE, DE L'ALUMINE, DE LA MAGNESIE, DE L'OXYDE DE TITANE, OU UN OXYDE MIXTE DE CEUX-CI, TRAITE PAR UN AGENT DE CHLORATION ET UN COMPOSE ORGANIQUE DE L'ALUMINE. APPLICATION A LA PRODUCTION DE POLYOLEFINES AYANT UN HAUT DEGRE D'ISOTACTICITE.
