The present invention provides a method for producing a polyamide using a terminal encapsulant, and a polyamide produced thereby, wherein the method is an eco-friendly process method without using a solvent as a catalyst and can prepare, by using a terminal encapsulant for suppressing side reaction, a polymer having a uniform molecular weight and a high conversion rate at a low temperature within a short polymerization time in comparison with a conventional polymerization method. La présente invention concerne un procédé de production d'un polyamide à l'aide d'un agent d'encapsulation de terminal, et un polyamide produit par ce procédé, le procédé étant un procédé de traitement respectueux de l'environnement sans utilisation de solvant en tant que catalyseur et pouvant préparer, en utilisant un encapsulant de terminal pour supprimer une réaction parasite, un polymère ayant un poids moléculaire uniforme et un taux de conversion élevé à basse température dans un temps de polymérisation court par comparaison avec un procédé de polymérisation classique. 본 발명은 촉매로 용매를 사용하지 않는 친환경 공정 방법으로 부반응을 억제하는 말단 봉지재를 이용하여 기존 중합 방법에 비교하여 저온에서 짧은 중합 반응시간 내에서 높은 전환율을 갖고 균일한 분자량의 고분자 중합이 가능한 말단 봉지재를 이용한 폴리아마이드 제조방법 및 이에 의해 제조된 폴리아마이드를 제공한다.
