BI-type compounds

Counter anion exchange reactions give stable RjIvIX Y (M = Sb, Bi) type compounds as shown in equations 225 ° and 226 . [Pg.794]

Non-aqueous polymerization is frequently carried out in an inert fluorinated solvent such as 1,1,2-trichloro 1,2,2-trifluoro ethane, perfluoro methyl cyclohexane, perfluoro dimethyl cyclobutane, perfluoro octane or perfluoro benzene. As the free radical initiator, a perfluorocarboxylic acid peroxide (RfC00)2, an azo bis type compound such as azobisisobutylo-nitrile, or a fluorine radical initiator such as N2F2 may be used. [Pg.386]

The free radical initiator may be a redox catalyst such as ammonium persulfate-sodium hydrogen sulfite, a perfluorocarboxylic acid peroxide (RfC00)2, or an azo bis type compound such as azob isisobutylonitrile. [Pg.386]
