摘要： 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.
