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:
(EN) Disclosed is a bio-degradable polyester composition, wherein, on the basis of the total weight of the bio-degradable polyester composition, the content by weight of styrene is 0.1 ppm - 30 ppm. According to the present invention, the content by weight of styrene selected to be added into the bio-degradable polyester composition formula is controlled to be 0.1 ppm - 30 ppm on the basis of the total weight of the bio-degradable polyester composition, which may guarantee that the bio-degradable polyester composition has excellent light transmittance and haze effect, and at the same time may also guarantee that the bio-degradable polyester composition has a proper ultraviolet resistance function without reducing the degradation rate of the bio-degradable polyester composition.
(FR) Cette invention concerne une composition de polyester biodégradable, dans laquelle, sur la base du poids total de la composition de polyester biodégradable, la teneur en poids de styrène est de 0,1 à 30 ppm. Selon la présente invention, la teneur en poids de styrène choisie pour être ajoutée dans la formule de la composition de polyester biodégradable est régulée pour être de 0,1 à 30 ppm sur la base du poids total de la composition de polyester biodégradable, ce qui peut garantir que la composition de polyester biodégradable a une excellente transmittance de la lumière et un excellent effet de trouble, et peut également garantir en même temps que la composition de polyester biodégradable a une fonction de résistance aux ultraviolets adéquate sans réduire sa vitesse de dégradation.
(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,苯乙烯的重量含量为0.1ppm-30ppm。本发明通过选用在可生物降解聚酯组合物配方中添加苯乙烯的重量含量基于可生物降解聚酯组合物的总重量控制在0.1ppm-30ppm时,可以保证可生物降解聚酯组合物具有优异的透光率和雾度效果,同时又可以保证可生物降解聚酯组合物具有适宜的抗紫外线功能,且不会降低可生物降解聚酯组合物的降解速率。
