Abstract[English]
Disclosed is a furan polyester composition, the furan polyester composition being mainly composed of 2,5-furandicarboxylic acid structural units and aliphatic diol structural units, and the polyester composition containing germanium and phosphite antioxidants. The furan polyester composition exhibits a color tone, heat resistance, and crystallinity that are all good, and can be used to prepare fibers, films, engineering plastics, and the like.[French]
L'invention concerne une composition de polyester furannique, la composition de polyester furannique étant principalement composée d'unités structurales d'acide 2,5-furandicarboxylique et d'unités structurales de diol aliphatique, et la composition de polyester contenant des antioxydants de germanium et de phosphite. La composition de polyester furannique présente une teinte de couleur, une résistance à la chaleur et une cristallinité qui sont toutes satisfaisantes, et peut être utilisée pour préparer des fibres, des films, des plastiques industriels et similaires.[Chinese]
