摘要： An antistatic polyester film and an antistatic coating liquid are provided. The antistatic polyester film includes a polyester substrate and an antistatic coating layer formed on the antistatic polyester film. The antistatic coating layer is formed by applying an antistatic coating liquid on the side surface of the polyester substrate by an in-line coating, and drying the antistatic coating liquid. The antistatic coating liquid includes an aqueous solvent, a conductive additive, and a water soluble polyester resin. Based on a total weight of the antistatic coating liquid being 100 wt %, the aqueous solvent ranges between 50 wt % and 85 wt %, the conductive additive ranges between 1 wt % and 20 wt %, and the water soluble polyester resin ranges between 2 wt % and 40 wt %.

摘要： Thermoplastic compositions include from about 15 wt % to about 98 wt % of a polybutylene terephthalate (PBT) component, from about 2 wt % to about 10 wt % of at least one brightening agent and from 0 wt % to about 83 wt % of at least one additional component. The PBT component includes PBT derived from post-consumer or post-industrial recycled (PCR) polyethylene terephthalate (PET). In particular, the PBT may be derived from the PCR PET by first depolymerizing the PCR PET to form a high purity bis(2-hydroxyethyl) terephthalate (BHET) monomer (e.g., greater than 95% purity), and then polymerizing the high purity BHET monomer with butane diol (BDO) to form the PBT. The thermoplastic compositions have an L* color value of at least about 94.

摘要： The present invention relates to a functional resin composition comprising a biomass-derived component, and more particularly to a functional resin composition comprising: a biomass-derived component; an aromatic dicarboxylic acid; an alcohol component; a chain extender; and a multifunctional compound. The biomass-derived component is biomass-derived succinic acid alone or a mixture of biomass-derived succinic acid alone and fossil-derived aliphatic dicarboxylic acid. The functional resin composition comprising these components has excellent processability, moldability, tearing strength and tensile strength, and does not easily change over time due to its excellent hydrolysis resistance.
