Abstract: front page image
(EN)The present invention relates to a method for producing a polyalkylenecarbonate resin. More specifically, provided is a method for producing a polyalkylenecarbonate resin in which, following the polymerization of polyalkylenecarbonate, a solution containing a solvent with melted polyalkylenecarbonate therein is mixed with water or an acid solution and by-products are removed by means of an extraction method, thus increasing the effectiveness of by-products removal over the existing effectiveness thereof and reducing the residual catalyst content, and thereby allowing the properties of the final product to be improved.
(FR)La présente invention concerne un procédé de fabrication d'une résine de poly(carbonate d'alkylène). Plus précisément, l'invention concerne un procédé de fabrication d'une résine de poly(carbonate d'alkylène) dans lequel, après la polymérisation de poly(carbonate d'alkylène), une solution contenant un solvant, avec du poly(carbonate d'alkylène) fondu dans celui-ci, est mélangée avec de l'eau ou une solution acide et les sous-produits sont éliminés au moyen d'un procédé d'extraction, augmentant ainsi l'efficacité d'élimination des sous-produits existants par rapport à l'efficacité existante de celui-ci et réduisant la teneur en catalyseur résiduel, ce qui permet d'améliorer les propriétés du produit final.
(KO)본 발명은 폴리알칼렌카보네이트 수지의 제조방법에 관한 것이다. 보다 구체적으로, 폴리알킬렌카보네이트의 중합 후에 폴리알킬렌카보네이트가 녹아 있는 용매 함유 용액을 물 또는 산용액과 섞어 추출법으로 부산물을 제거함으로써, 기존 보다 부산물의 제거 효율이 증가하고 잔류 촉매의 함량을 감소시켜 최종 제품 물성을 향상시킬 수 있는 폴리알킬렌카보네이트 수지의 제조방법이 제공된다.
