    摘要： The incorporation of nanosized metal particles into cyclodextrin-containing material leads to a “reactive” barrier material having excellent barrier properties. Also, it has been found that the presence of nanosized metal or metal alloy particles in a barrier material such as thermoplastic material, wherein said material comprises cyclodextrin derivatives, may be advantageous in achieving excellent barrier properties. The barrier material of the present invention may provide improved barrier resistance to a variety of permeants and/or impurities. The diffusion of volatile substances through the barrier material may be prevented by adding compatible derivatized cyclodextrin and nanosized metal particles to the material used. Accordingly, the inventive material also is suitable for many applications including food-contact packaging, flexible packaging to dispose of adult and baby diapers, incontinent products, hospital and household waste and also for packaging pharmaceutical products, medical devices and dental materials.

    摘要： Thermoplastic polymer compositions, films, containers, laminates and fibers can comprise a modified polymer. The said modified polymer having a moiety comprising a half-ester reaction product of cyclodextrin and metal and/or organic group covalently bonded to some portion of the half-acid moieties. The cyclodextrin compound, grafted to the polymer structure, can scavenge impurities, permeants, or other undesirable volatile contaminants. The cooperation between the modified polymer's carboxylic acidic groups, basic groups and grafted cyclodextrin can provide active barrier properties to a film, web, fiber or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film, web or fiber preventing the permeant from passing into the interior of a container, or the contaminant can be scavenged from the enclosed headspace or surrounding environment.
