Abstract[English]
Thermoplastic compositions include: a copolyester elastomer including a polybutylene terephthalate (PBT) moiety and an elastomer moiety; and from greater than 0. 1 wt% to 9 wt% of at least one brightening agent. The copolyester elastomer is formed according to a process including (1) forming the PBT moiety from a high purity terephthalic moiety; and (2) polymerizing the PBT moiety with the elastomer moiety to form the copolyester elastomer, wherein the high purity terephthalic moiety is derived from post- consumer, pre-consumer or post-industrial recycled (PCR) polyethylene terephthalate (PET). The PBT moiety includes PBT derived from post-consumer, pre-consumer or post-industrial recycled (PCR) polyethylene terephthalate (PET), the high purity terephthalic moiety has a purity of at least about 95%, and the thermoplastic composition has an L* color value of at least 80 as determined according to a CIELab color space standard. Methods for forming the copolymer elastomer and compositions including it are also described.[French]
Des compositions thermoplastiques comportent : un élastomère de copolyester comportant une fraction poly(butylène téréphtalate) (PBT) et une fraction élastomère ; et de plus de 0,1 % en poids à 9 % en poids d'au moins un azurant. L'élastomère de copolyester est formé selon un processus consistant (1) à former la fraction PBT à partir d'une fraction téréphtalique de haute pureté ; et (2) à polymériser la fraction PBT avec la fraction élastomère pour former l'élastomère de copolyester, la fraction téréphtalique de haute pureté étant dérivée de poly(éthylène téréphtalate) (PET) de post-consommation, de pré-consommation ou de recyclage post-industriel (PCR). La fraction PBT comporte du PBT dérivé de poly(éthylène téréphtalate) (PET) de post-consommation, de pré-consommation ou de recyclage post-industriel (PCR), la fraction téréphtalique de haute pureté présente une pureté d'au moins environ 95 %, et la composition thermoplastique présente une valeur de couleur L* d'au moins 80 telle que déterminée selon une norme d'espace colorimétrique CIELab. Des procédés en vue de la formation de l'élastomère copolymère et des compositions le comportant sont également décrits.
