Title (EN) BIO-DEGRADABLE POLYESTER COMPOSITION
(FR) COMPOSITION DE POLYESTER BIODÉGRADABLE
(ZH) 一种可生物降解聚酯组合物
Abstract: front page image
(EN)Disclosed is a bio-degradable polyester composition, wherein, on the basis of the total weight of the biodegradable polyester composition, the content by weight of glycidyl methacrylate is 0.05 ppm -10 ppm. According to the present invention, by means of adding a trace of glycidyl methacrylate in a formula of the bio-degradable polyester composition, the content by weight of glycidyl methacrylate which ultimately remains in the biodegradable polyester composition is controlled to be 0.05 ppm -10 ppm, thus the compatibility of aliphatic-aromatic polyester and polylactic acid base materials in the biodegradable polyester composition may be greatly improved so that the biodegradable polyester composition has excellent membrane material surface performance, and phenomena such as crystal points appearing on a membrane material due to the fluctuation of processing technology may be avoided.
(FR)L'invention concerne une composition de polyester biodégradable dont la teneur en poids en méthacrylate de glycidyle est de 0,05 ppm à 10 ppm, par rapport au poids total de la composition de polyester biodégradable. Selon la présente invention, grâce à l'addition d'une trace de méthacrylate de glycidyle à une formulation de la composition de polyester biodégradable, la teneur en poids en méthacrylate de glycidyle qui finalement reste dans la composition de polyester biodégradable est régulée à une valeur de 0,05 ppm à 10 ppm, de sorte qu'il est possible d'améliorer fortement la compatibilité du polyester aliphatique-aromatique et de matériaux à base de poly(acide lactique) dans la composition de polyester biodégradable; la composition de polyester biodégradable présente ainsi d'excellentes performances de surface en tant que un matériau membranaire, et il est possible d'éviter des phénomènes tels que des pointes cristallines apparaissant sur un matériau membranaire en raison des fluctuations de la technologie de traitement.
(ZH)本发明公开了一种可生物降解聚酯组合物,其中,基于可生物降解聚酯组合物的总重量,甲基丙烯酸缩水甘油酯的重量含量为0.05ppm-10ppm。本发明通过选用在可生物降解聚酯组合物配方中,通过添加微量的甲基丙烯酸缩水甘油酯,控制最终残留在可生物降解聚酯组合物中甲基丙烯酸缩水甘油酯的重量含量为0.05ppm-10ppm,可以极大的提高可生物降解聚酯组合物中脂肪族-芳香族聚酯和聚乳酸基材的相容性,使得可生物降解聚酯组合物具有优异的膜材表面性能,且不会由于加工工艺的波动导致膜材出现晶点等现象。
