| description | The present invention relates to a method for the decolorization and depolymerization of a colored polymer containing an ester functional group and, specifically, to a method for the decolorization and depolymerization of a colored polymer containing an ester functional group, in which, by adding compounds represented by chemical formula 1 as an extractant and an additive, depolymerization is possible at a lower temperature, the yield of a target product can be increased, and color-expressing foreign substances can be removed from the colored polymer.
La présente invention se rapporte à un procédé de décoloration et de dépolymérisation d'un polymère coloré contenant un groupe fonctionnel ester et, plus particulièrement, à un procédé de décoloration et de dépolymérisation d'un polymère coloré contenant un groupe fonctionnel ester, dans lequel, par l'addition de composés représentés par la formule chimique 1 comme agent d'extraction et d'un additif, une dépolymérisation est possible à une température inférieure, le rendement d'un produit cible peut être accru, et des substances étrangères exprimant une couleur peuvent être retirées du polymère coloré.
본 발명은 에스테르 작용기를 포함하는 유색 고분자의 탈색 및 해중합 방법에 관한 것으로, 상세하게는 하기 화학식 1로 표시되는 화합물을 추출제 및 첨가제로 부가함으로써, 보다 낮은 온도에서도 해중합이 가능하고, 목적 생성물의 수율을 높일 수 있으며, 유색 고분자로부터 색을 발현하는 이물질을 제거 가능한 에스테르 작용기를 포함하는 유색 고분자의 탈색 및 해중합 방법에 관한 것이다. |
