Abstract
Process for the production of polymers and copolymers of isobutylene, characterized in that the polymerization reaction is carried out in the presence of a catalyst system that includes: I) an organometallic compound of aluminum which has by formula R al (yr') x Wherein r is hydrogen or an alkyl, cycloalkyl, aryl, simple or substituted residue; r'is a hydrocarbon radical selected from those indicated for r; and it is an atom of oxygen or sulfur, or it can also be hydrogen, in which case it will be attached to the hydrocarbon radicals; x is a halogen atom; y Ii) a cocatalyst selected from the following: A) brºnsted acids B) alkyl halides, organic or inorganic acid halides, or compounds containing activated halogen atoms, C) lewis acids, D) compounds of the formula x'n me y'm, wherein x'is a halogen atom; y'is oxygen, sulfur or a functional group selected from the groups alkoxyls, esters, amides, alkyls, simple or substituted, cycloalkyls, aromatics, arenas, phosphines, acetylacetonates, and oximes; me is a metal selected from ti, sn, zn, si, b, al, hg, pb, w, sb, ge, v, zr, as, bi and mo.
