PROCESS FOR PREPARATION OF BUTYL RUBBER HAVING BROAD MOLECULAR WEIGHT DISTRIBUTION

摘要

The preparation method of butyl polymer has wide molecular weight distribution. It include: the mono-olefin monomer of contact procedure C4 to C8 and the temperature range of C4 to C14 multi-olefin monomers be about -100 °C to about+50 °C in diluent and catalyst mixture includes major amount of dialkylalumium halide, a small amount of monoalkylaluminum dihalide and micro aikyiaiurnirsoxan beta.
