Title (EN) METHOD FOR MEASURING POLYMER MODIFICATION RATIO
(FR) PROCÉDÉ DE MESURE DU TAUX DE MODIFICATION DE POLYMÈRE
(KO) 중합체 변성률 측정 방법
Abstract:
(EN) The present invention relates to a method for measuring a polymer modification ratio and, more specifically, provides a method for measuring a polymer modification ratio, the method comprising the steps of: preparing a first solution by dissolving a polymer mixture comprising a modified polymer and an unmodified polymer in a first solvent; injecting the first solution into a column filled with an adsorbent; allowing the modified polymer to be adsorbed on the adsorbent and eluting the first solution in which the unmodified copolymer is dissolved; transferring the eluted first solution to a detector; injecting a second solvent into the column to elute a second solution in which the adsorbed modified polymer is dissolved; and transferring the eluted second solution to the detector.
(FR) La présente invention concerne un procédé de mesure d'un taux de modification de polymère et, plus spécifiquement, un procédé de mesure d'un taux de modification de polymère, le procédé comprenant les étapes de : préparation d'une première solution par dissolution d'un mélange de polymères comprenant un polymère modifié et un polymère non modifié dans un premier solvant; injection de la première solution dans une colonne remplie d'un adsorbant; attente que le polymère modifié soit adsorbé sur l'adsorbant et élution de la première solution dans laquelle le copolymère non modifié est dissous; transfert de la première solution éluée vers un détecteur; injection d'un deuxième solvant dans la colonne pour éluer une deuxième solution dans laquelle le polymère modifié adsorbé est dissous; et transfert de la deuxième solution éluée vers le détecteur.
(KO) 본 발명은 중합체 변성률 측정 방법에 관한 것으로, 보다 상세하게는 변성 중합체 및 미변성 중합체를 포함하는 중합체 혼합물을 제1 용매에 용해시켜 제1 용액을 준비하는 단계; 상기 제1 용액을, 흡착제가 충진된 컬럼(column)에 주입시키는 단계; 상기 변성 중합체를 상기 흡착제에 흡착시키고, 상기 미변성 공중합체가 용해된 제1 용액을 용출시키는 단계; 상기 용출된 제1 용액을 검출기로 이송시키는 단계; 제2 용매를 상기 컬럼에 주입시켜 상기 흡착된 변성 중합체가 용해된 제2 용액을 용출시키는 단계; 및 상기 용출된 제2 용액을 상기 검출기로 이송시키는 단계를 포함하는 중합체 변성률 측정 방법을 제공한다.
