Title (EN) POLYESTER SEGMENTED COPOLYMER AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
(FR) COPOLYMÈRE SEGMENTÉ DE POLYESTER, SON PROCÉDÉ DE PRÉPARATION ET SON APPLICATION
(ZH) 一种聚酯嵌段共聚物及其制备方法与应用
Abstract:
(EN) The present invention discloses a polyester segmented copolymer, characterized by the structure shown in the formula (I). The present invention further discloses a method for preparing the polyester segmented copolymer. The present invention polymerizes a silicon-containing unit into a polyester molecular chain by copolymerization, and the resultant copolymer has excellent low-temperature resistance and lower surface tension, addressing the issue of non-resistance of polyester resins to low temperatures, and expanding applications of polyester resins in the fields of fibers, thin films, blow molding, and engineering plastics.
(FR) La présente invention concerne un copolymère segmenté de polyester, caractérisé par la structure répondant à la formule (I). La présente invention concerne en outre un procédé de préparation du copolymère segmenté de polyester. La présente invention polymérise une unité contenant du silicium dans une chaîne moléculaire de polyester par copolymérisation, et le copolymère résultant a une excellente résistance à basse température et une tension de surface inférieure, résolvant le problème de non-résistance de résines de polyester aux basses températures, et élargissant les possibilités d'applications de résines de polyester dans les domaines des fibres, des films minces, du moulage par soufflage et des plastiques techniques.
(ZH) 本发明公开了一种聚酯嵌段共聚物,其特征在于,其结构如下式(I)所示;本发明同时公开了一种聚酯嵌段共聚物的制备方法。本发明通过共聚的方法,将含硅单元聚合至聚酯分子链中,所得到的共聚物具有优异的耐低温性能和较低的表面张力,改善了聚酯树脂不耐低温的特点,拓展了其在纤维、薄膜、吹塑和工程塑料领域的应用空间。 A n-B t (I)
