Butyl rubber since industrial production since the raw material line, production process and structure has been little change in the polymerization vessel, generally using methyl chloride as a diluent, aluminum trichloride as catalyst, the amount of control that can be adjusted both monomers conversion. Product according to the class of unsaturation, isoprene is generally used in an amount from 1.5% to 4.5% in the amount of isobutylene conversion was 60% to 90%. The polymerization temperature was maintained at -100 ℃ (using ethylene and propylene as a coolant). Butyl rubber polymerization reaction is carried out based on positive ions, the reaction temperature is low, high speed, heat set, and polymer molecular weight decrease rapidly with increasing temperature. Thus, the rapid discharge of the heat of polymerization in order to control the reaction at a constant low temperature, is a major production problems. Polymerizer (see Figure) having a large heat transfer area and the use of the central conduit of a column equipped with a tubular reactor. When rotated at high speed by operating the lower portion of the agitator, the circulation amount is increased, thus ensuring uniform temperature of each point within the reactor. Butyl rubber blends to improve the shortcomings of poor, since 1960 there has been a halogenated butyl rubber. This rubber is a butyl rubber dissolved in an alkane or cycloalkane, the halogenation reaction in the system under stirring. It contains approximately 2% bromine or chlorine 1.1% ~ 1.3%, respectively, said brominated butyl rubber and chlorinated butyl rubber. After halogenated butyl rubber vulcanization speed is greatly improved, improved and blended with other properties of rubber vulcanized were, there was a marked increase adhesion. Halogenated butyl rubber in addition to a general purpose butyl rubber, it is particularly suitable for the production of a tubeless tire inner sealing layer, radial tire sidewall and adhesives.
