Ketonic type polymers can be obtained by acylating dibenzo 18 crown 6 with aliphatic dibacic acids in polyphosphoric acid.The reaction process was influenced by the molecular chain length of dibasic acids.When the molecular chain length of dibasic acids was too short
the reaction process was hindered
and colored product was given out because of much sidereaction.The optimum reaction time and temperature were investigated.High molecular weight condensation polymers of dibenzo-18-crown 6 with sebacic acid were produced by controlling of the reaction conditions
