| 摘要 |
The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition conta ins cyclodextrin and particles of activated carbon. The composition can scav enge thermal decomposition products that can be produced during melt process ing of a polymer, contaminants inherent in a polymer, or other types of impu rities from a polymer matrix that otherwise may elute into the air, a water supply, or an ingestible material such as a food, a drug, or a beverage. Oth er aspects of the invention are blends of the composition with polymeric mat erials, methods of making blends, articles containing the composition, and m ethods of making articles containing the composition. |
