Colored polyester thermoplastic materials comprised of poly(oxyalkylenated) compounds as colorants and specific surfactants as diluents |
摘要 |
This invention relates to colored polyester thermoplastics comprised of polymeric colorants having poly(oxyalkylene) moieties and/or anionic dye/quatenary ammonium substantially inorganic salt-free colorant complexes mixed with diluents selected from the group consisting essentially of sorbitan (C8-C22) monoesters, ethoxylated sorbitan (C8-C22) monoesters, mixtures thereof of sorbitan (C8-C22) monoesters and ethoxylated sorbitan (C8-C22) monoesters, ethoxylated nonyl-phenol ethers, ethoxylated dodecylphenol ethers, mixtures thereof of said ethoxylated nonyl-phenol ethers and ethoxylated dodecylphenol ethers, and mixtures of (i) sorbitan (C8-C22) monoesters or ethoxylated sorbitan (C8-C22) monoesters and (ii) ethoxylated nonyl-phenol ethers or ethoxylated dodecylphenol ethers. Such diluents facilitate the introduction of the preferred polymeric colorants within feedstock polyester during the extrusion or injection molding process and provide a significant improvement over traditional polyester article colorants. The inventive colored polyester thermoplastic may be molded into any shape or form; however, plastics are commonly utilized as containers for liquids, such as soft drinks. A method of coloring polyester during an extrusion or injection molding procedure utilizing the inventive colorant/diluent formulations are also provided.
