The purification and polymerization of the monomer I were studied. Crude Ⅰ contained compounds Ⅱ
Ⅲ and Ⅳ as impurities
whivh were removed by low temperature crystallization followed by filtration throudh a short alumina column. The monomer I was polymerized by UV-irradiation in the presence of Hg with or without solvent. Polyperfluorooxaalkyl triaizne Ⅴ thus obtained showed good thermal stability. In the main chain of the polymer there was no weak unit of uncyclized ring. polymer Ⅴ had an average molecular weightof ca.1.33—2.0×104(D.P.=27—42) and the temperature of 10%weight loss in nitrogen was 340℃.
