Abstract

L'INVENTION CONCERNE UN PROCEDE AMELIORE POUR PREPARER UN COPOLYMERE D'ETHYLENE ET DE PROPYLENE. ON COPOLYMERISE DE L'ETHYLENE ET 15 A 250MOLES DE PROPYLENE PAR RAPPORT A L'ETHYLENE DANS UNE PHASE VAPEUR PRATIQUEMENT DEPOURVUE DE SOLVANT ET EN PRESENCE D'UN CATALYSEUR CONSTITUE D'UNE SUBSTANCE SOLIDE ET D'UN COMPOSE ORGANO-ALUMINIQUE, CETTE SUBSTANCE SOLIDE CONTENANT UN COMPOSE SOLIDE MINERAL CONTENANT DU MAGNESIUM ET UN COMPOSE DE TITANE ETOU UN COMPOSE DE VANADIUM. L'INVENTION CONCERNE EN PARTICULIER LA PREPARATION DE COPOLYMERES SOUPLES OU DEMI-DURS D'ETHYLENE ET DE PROPYLENE AYANT UN INDICE DE FLUIDITE DE 0,01 A 10 ET UNE DENSITE DE 0,850 A 0,910.
