Method for tagging thermoplastic materials with near infrared fluorophores |
| 摘要 |
<p>Provided are compounds effective in a method for "marking" or "tagging" a thermoplastic polymeric material by incorporating one or more thermally stable, near infrared fluorescing compounds therein by admixing or copolymerizing or by blending with certain condensation polymers containing one or more near infrared fluorescing compounds copolymerized or admixed therein and a method for separating or sorting a mixture of thermoplastic containers such as bottles. In particular, provided are thermoplastic polymer compositions tagged with such compounds or residues.</p> |
