Title (EN) METHOD FOR PREPARING POLYALKYLENE CARBONATE RESIN
(FR) PROCÉDÉ DE PRÉPARATION DE RÉSINE DE CARBONATE DE POLYALKYLÈNE
(KO) 폴리알킬렌카보네이트 수지의 제조방법
Abstract: front page image
(EN)The present invention relates to a method for preparing a polyalkylene carbonate resin and, more specifically, provides a method for preparing a polyalkylene carbonate resin, the method purifying a reaction mixture by removing by-products with a large quantity of water after polymerizing a polyalkylene carbonate, and making the catalyst content in the reaction mixture to be less than 1 wt% by carrying out a first purification method using a filter in a step, which proceeds after the purification of the reaction mixture, of removing a catalyst residue, thereby preventing the decomposition of polymers and improving the physical properties and quality of a final resin product.
(FR)La présente invention concerne un procédé de préparation d'une résine de carbonate de polyalkylène et, plus spécifiquement, concerne un procédé de préparation d'une résine de carbonate de polyalkylène, le procédé comprenant la purification d'un mélange réactionnel par élimination des sous-produits avec une grande quantité d'eau après la polymérisation d'un carbonate de polyalkylène, et le fait de porter la teneur en catalyseur dans le mélange réactionnel à une valeur inférieure à 1 % en poids en effectuant un premier procédé de purification à l'aide d'un filtre dans une étape, qui a lieu après la purification du mélange réactionnel, consistant à éliminer un résidu de catalyseur, ce qui permet d'empêcher la décomposition de polymères et d'améliorer les propriétés physiques et la qualité d'un produit de résine final.
(KO)본 발명은 폴리알칼렌카보네이트 수지의 제조방법에 관한 것이다. 보다 구체적으로, 폴리알킬렌카보네이트의 중합 후 다량의 물로 부산물을 제거하여 반응혼합물을 정제하고, 또한 이후 진행되는 촉매 잔사를 제거하는 과정에서 필터를 이용한 1차 정제방법을 수행하여 반응 혼합물 중의 촉매 함량이 1 중량% 미만이 되도록 함으로써, 고분자의 분해를 방지하고 최종 수지 제품의 물성과 품질을 향상시킬 수 있는 폴리알킬렌카보네이트 수지의 제조방법이 제공된다.
