Mouse glue manufacturers need butyl rubber 532

Butyl rubber from industrial production since the route of raw materials, production processes and structure the polymerization reactor has been little change in the general use of methyl chloride as diluent, aluminum chloride as a catalyst, which can control both the amount of monomer conversion rate. Product according to level of unsaturation, isoprene is generally used in an amount from 1.5% to 4.5% of the amount of isobutene conversion was 60% to 90%. The polymerization temperature was maintained at -100 ℃ (ethylene and propylene using as coolant). Butyl rubber polymerization reaction is carried out based on positive ions, the reaction temperature is low, fast, centralized heat, and the molecular weight of the polymer decreased dramatically with increasing temperature. Therefore, in order to control the rapid discharge of the heat of polymerization reaction at a constant low temperature, it is a major production problems.
