PROCESS FOR THE PREPARATION OF ETHYLENE-A-OLEFIN FLEXIBLE COPOLYMERS OR SEMIDERS |
| abstract |
THE SUBJECT OF THE INVENTION IS A PROCESS FOR THE PREPARATION OF SOFT OR SEMI-HARD ETHYLENE-A-OLEFINE COPOLYMERS HAVING AN INTRINSIC VISCOSITY OF 3.0 TO 10DLG MEASURED IN DECALINE AT 135C AND A DENSITY OF 0.850 TO 0.910, AND THE AINSIMERS OBTAINED. ACCORDING TO THE INVENTION, ETHYLENE AND 4 TO 250 MOLES OF AN A-OLEFIN ARE COPOLYMERIZED WITH RESPECT TO ETHYLENE IN THE VAPOR PHASE SENSITIVELY FREE OF SOLVENT, AT A TEMPERATURE OF 10 TO 80C, AT A CONCENTRATION OF HYDROGEN IN THE VAPOR PHASE FROM 0 TO 5 MOLES AND IN THE PRESENCE OF A CATALYST WHICH CONTAINS A SOLID SUBSTANCE AND AN ORGANOALUMINUM COMPOUND, THE SOLID SUBSTANCE CONTAINING A SOLID INORGANIC SUPPORT CONTAINING MAGNESIUM AND A TITANIUM COMPOUND AND OR A VANADIUM COMPOUND. |
