| Abstract: | The trifluoride catalysing copolymerization of ethylene oxide and tetrahydrofuuran has been studied in the presence of 1,4-butanediol as cocatalyst. It has been found suitable technological conditions of solvent polymerization and bulk polymerization. In both cases, the resulting polymerizate contains about 8% by weight of oligomeric cyclic ethers. It has been found out convenient purifing method of crude product. The content of cyclic oligomeric ethers in polymerizate can be reduced to below 1% by this purified method. |
