Title (EN) POLYTRIMETHYLENE ETHER GLYCOL AND PREPARATION METHOD THEREFOR
(FR) POLYTRIMÉTHYLÈNE ÉTHER GLYCOL ET SON PROCÉDÉ DE PRÉPARATION
(KO) 폴리트리메틸렌 에테르 글리콜 및 이의 제조 방법
Abstract:
(EN) The present invention relates to a polytrimethylene ether glycol and a preparation method therefor, the preparation method effectively removing various by-products and oligomers from a polytrimethylene ether glycol product without long-term exposure to a high temperature, thereby enabling a deviation in molecular weight to be reduced through the removal of various by-products and low-molecular-weight oligomers.
(FR) La présente invention concerne un polytriméthylène éther glycol et son procédé de préparation, le procédé de préparation éliminant efficacement divers sous-produits et oligomères contenus dans un produit de polytriméthylène éther glycol sans exposition de longue durée à une température élevée, ce qui permet de réduire un écart de masse moléculaire par l'élimination de divers sous-produits et oligomères de faible masse moléculaire.
(KO) 본 발명에 따른 폴리트리메틸렌 에테르 글리콜 및 이의 제조 방법은, 고온에 장시간 노출하지 않으면서도 폴리트리메틸렌 에테르 글리콜 생성물로부터 각종 부산물 및 올리고머를 효과적으로 제거함으로써, 각종 부산물과 저분자량의 올리고머가 제거되어, 분자량 편차를 줄일 수 있다는 특징이 있다.
