Zusammenfassung:	The present invention relates to a method to produce polyepichlorohydrin-polyols and polyglycidyl azide-polyols. The present invention includes a step of forming a trifluoride-diol complex by heating after mixing diol with trifluoride-etherate (BF3-Etherate) and a step of synthesizing a compound displayed in chemical formula 1 by supplying epiklohydrin to the complex. The step of synthesizing the compound provides a polyepichlorohydrin-polyol producing method which is processed with a melting polymerization reaction. In the chemical formula 1, n and m are natural numbers from 1 to 50, the sum of n and m is equal to or less than 50, and R1 is an alkylene group. The present invention can solve problems of risk of explosion during synthesizing and refining processes by not using methylene chloride when synthesizing polyglycidyl azide. 본 발명은 폴리에피클로로하이드린-폴리올 및 폴리글리시딜아자이드-폴리올의 제조방법에 관한 것이다. 본 발명은 다이올과 트리플루오라이드-에테르염(BF3-Etherate)를 혼합한 후 가열하여 트리플루오라이드-다이올 복합체를 형성하는 단계 및 상기 복합체에 에피클로하이드린을 공급하여 하기 화학식 1로 표시되는 화합물을 합성하는 단계를 포함하고, 상기 화합물을 합성하는 단계는 용융 중합 반응으로 진행되는 것을 특징으로 하는 폴리에피클로로하이드린-폴리올의 제조방법을 제공한다. [화학식 1]상기 화학식 1에서, n 및 m은 1 내지 50인 자연수이고, n과 m의 합은 50 이하이며, R1은 알킬렌기이다. 본 발명에 따르면, 폴리글리시딜아자이드 합성 시 메틸렌클로라이드를 사용하지 않음으로써, 합성 및 정제시 폭발의 위험성을 해결할 수 있다.
