| Abstract: | lame restarding poly(dibromophenylene oxide) was prepared by five catalystic systems:K3Fe (CN )6, Cu (NO3 ) 2 3H2O-CH3CN, CuC12 2HZ ocDMF, CuC122H2O-DMSO andCuCl22H2O-NaOCH3, respectively.For three catalytic systems in them, the effects of reaction temperature, time, molar ratio and catulytic concentration on the polymer yield were investigated,and optimum teaction conditions were found. The reaction machanisms were been indicated for different kinds of catalytic system. Different melting point of .poly (dibromophenylene oxide) by preparation with various catalytic system demonstrated their different activity which induced differentistion of polymerization form and polymerisation degree. The molecular weights of polymer distributed from high to low,which was used effectively by demonstration from theory of flame restarding. |
