Title (EN) POLYLACTIC ACID COPOLYMER AND METHOD FOR PREPARING SAME
(FR) COPOLYMÈRE DE POLY(ACIDE LACTIQUE) ET PROCÉDÉ POUR SA PRÉPARATION
(KO) 폴리락트산 공중합체 및 그 제조방법
Abstract: front page image
(EN)The present invention relates to a polylactic acid copolymer and a method for preparing the same and, more specifically, to a polylactic acid copolymer with improved elasticity and thermal stability compared to a polylactic acid homopolymer, by including as repeating units, (A) lactic acid, and (B) a monocyclic, polycyclic, or fused cyclic compound having a hydroxyl-tetramethylene-oxy-hydrocabon group at the terminal, and a method for preparing the same.
(FR)La présente invention concerne un copolymère de poly(acide lactique) et un procédé pour sa préparation et, plus particulièrement, un copolymère de poly(acide lactique) présentant une élasticité et une stabilité thermique améliorées par rapport à un homopolymère de poly(acide lactique), par inclusion, en tant que motifs récurrents, de (A) acide lactique et de (B) un composé cyclique monocyclique, polycyclique ou condensé présentant un groupe hydroxyl-tétraméthylène-oxy-hydrocarboné au niveau l'extrémité, et un procédé pour sa préparation.
(KO)본 발명은 폴리락트산 공중합체 및 그 제조방법에 관한 것으로서, 보다 상세하게는, 반복단위로서 (A) 락트산; 및 (B) 말단에 히드록시-테트라메틸렌-옥시-탄화수소 기를 갖는 모노사이클릭, 폴리사이클릭 또는 융합 사이클릭 화합물;을 포함함으로써, 폴리락트산 단독 중합체 대비 신축성 및 열 안정성이 개선된 폴리락트산 공중합체 및 그 제조방법에 관한 것이다.
