Abstract 1. PROCESS FOR THE PRODUCTION OF BUTYL RUBBER THROUGH THE COPOLYMERIZATION OF SIOLBUTYLENE AND ISOPRENE WHEREIN THE IMPROVEMENT COMPRISES CONDUCTING THE COPOLYMERIZATION REACTION IN THE PRESENCE OF A CATALYST SYSTEM CONSISTING ESSENTIALLY OF: (A) A METALORGANIC COMPOSITION OF ALUMINUM REPRESENTED BY THE FORMULA AIR3 OR AIR2X WHEREIN X IS AN ATOM OF HALOGEN, AND R IS A HYDROCARBON RADICAL HAVING FROM 1 TO 10 CARBON ATOMS, OR HYDROGEN; (B) A HALOID OF AN INORGANIC ACID REPRESENTED BY THE GENERAL FORMULA ZNMEXMYP IN WHICH ME IS AN ELEMENT BELONGING TO THE 5*, 6* OR 7* GROUP OF THE PERIODIC SYSTEM; N AND M ARE WHOLE NUMBERS; P IS A WHOLE NUMBER OR ZERO AND THE SUM 2N+M+P IS EQUAL TO THE VALENCY OF SAID ELEMENT; Z IS OXYGEN OR SULPHUR; X IS A HALOGEN ATOM; Y IS AN ORGANIC RESIDUE SELECTED FROM THE ALKYLIC, ACRYLIC, CYCLOHEXYLIC, ETHERIC, AMMIDIC, ACETYLACETONIC AND OXIMIC FUNCTIONAL GROUPS; AND WHEREIN THE MOLAR RATIO OF COMPOUND (B) TO COMPOUND (A) IS BETWEEN 0.5 AND 10-4.
