  • Patent number: 8759279
    Abstract: A film formed from a biodegradable polymer matrix within which is contained at least one fragrance is provided. The ability to incorporate a fragrance into the polymer matrix is achieved in the present invention by controlling a variety of aspects of the film construction, including the nature of the fragrance, the nature of the biodegradable polymer, the manner in which the polymer matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the biodegradable polymer. In this manner, the costly and time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch are not required. Furthermore, to obtain a balance between the ability of the fragrance to release the desired odor during use and likewise to minimize the premature exhaustion of the odor during melt processing, the fragrance is selected to have a boiling point (at atmospheric pressure) within a certain range, such as from about 125° C.

  • Publication number: 20120071592
    Abstract: The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition contains cyclodextrin and particles of activated carbon. The composition can scavenge thermal decomposition products that can be produced during melt processing of a polymer, contaminants inherent in a polymer, or other types of impurities 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. Other aspects of the invention are blends of the composition with polymeric materials, methods of making blends, articles containing the composition, and methods of making articles containing the composition.

  • Patent number: 8129450
    Abstract: Durable and disposable articles are provided which include a thermoplastic polymer composition, which includes a blend of a polymer and a modified polymer. The modified polymer has covalently bonded pendant substituents derived from cyclodextrin. The articles can be a films, coatings, nonwoven webs, or monolithic articles. An article can have the polymer composition as one part of the article, such as in one distinct area of the article, or on the surface of the article, for example as a coating or surface film. The article can be, for example, a multilayer barrier film, a nonwoven sheet or pad, an absorbent article, or a storage container.

  • Publication number: 20110281980
    Abstract: A composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners may be prepared from monomers by an all-aqueous solution polymerization.

  • Patent number: 8008376
    Abstract: Disclosed are plasticizer compositions including cyclodextrin derivatives, a flexible PVC composition with suppression of the migration of a plasticizer containing the same, and a manufacturing method thereof. The manufacturing method of the flexible PVC composition of the present invention includes steps of (S1) preparing cyclodextrin derivatives; (S2) mixing the cyclodextrin derivatives, PVC and a low molecular weight liquid plasticizer to form a plastisol; and (S3) heating the plastisol to form a solution and cooling the solution. The manufacturing method PVC-1 of the present invention may be useful to mass-produce flexible PVC with suppression of the migration of a plasticizer in a simple and economic manner without using solvents since the cyclodextrin derivatives are used as a compound that can suppress the migration of a plasticizer. The flexible PVC has an effect of reducing an amount of the migrated plasticizer without deterioration in its physical properties.
