TREATMENT OF THERMOPLASTIC MATERIALS WITH CHELATING AGENTS, AND RELATED PRODUCTS |
| 摘要 |
The metal content of a thermoplastic composition containing an undesirably high concentration of metal can be reduced by adding to 100 parts by weight of the composition at least about 0.3 parts by weight of a chelating agent and sufficient water to chelate metal in the composition to form chelated metal in the composition, and then removing at least some of the chelated metal from the composition.
