  • Patent number: 8188185
    Abstract: A biodegradable packaging film is provided. The film is formed from a blend that contains a thermoplastic starch and polylactic acid. Starch is a relatively inexpensive natural polymer that is also renewable and biodegradable. Polylactic acid is likewise an inexpensive synthetic polymer that is biodegradable and renewable, yet also capable of providing increased tensile strength to the film. Although providing a good combination of biodegradability/renewability and increased tensile strength, the polylactic acid is also relatively rigid and can result in films having a relatively high stiffness (e.g., high modulus of elasticity) and low ductility. While more ductile than polylactic acid, the thermoplastic starch is often difficult to melt process in film forming processes and very sensitive to moisture and water vapor, reducing its ability to be used as a stand alone packaging film.

  • Publication number: 20100249321
    Abstract: Ethylenically unsaturated, particularly acrylic, monomers are polymerised using a catalyst system including a manganese carbonyl initiator, an organic halogen reactive substrate and an allylic halide chain termination agent. Desirably the manganese carbonyl initiator is a dimanganese compound, particularly dimanganese decacarbonyl (Mn2(CO)10). The catalysis mechanism appears to involve initiator homolysis, abstraction of halogen from the reactive substrate forming an organic free radical which acts as a chain initiator for polymerisation and eventual reaction of the propagating chain radical with the chain terminating agent. The speed or extent of reaction may be modified by the inclusion of Lewis acids in the reaction mixture. The resulting polymers are telechelic and may have different end groups. The polymers can be reacted further to functionalise them and/or to form block copolymers.

    Abstract: A modified bioreactor support material having high surface area for removing a contaminant (16) from fluids can include a substrate (10) having a functionalized surface, The functionalized surface can have inorganic or organic non-living functional groups, such that the functional groups bind to or chemically alter the contaminant. A method for making a modified bioreactor support material can include activating a suitable substrate (10) and attaching a biologically-derived functional group carrier such as living microbes (18) or non-living materials (14) derived from living materials to the activated substrate (10).

  • Patent number: 7605199
    Abstract: Thermoplastic polymer compositions, films, continues, closures, laminates can comprise a modified vinyl polymer said modified polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, locked into the polymer structure, can absorb impurities, permeants, or other undesirable volatile materials. The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.

  • Publication number: 20090253609
    Abstract: The invention relates to novel hybrid compounds comprising at least one silicone entity (Sil) in which at least one of the silicons of Sil is substituted by at least one unit—Ro-B, B being an entity of a variable nature, for example polymer, hydrocarbonated or mineral, selected from a group comprising polyols (e.g. saccharides), silicones, polyalkylene glycols, polyamides, polyesters, polystyrenes, alkyls, alkenyls, alkynyls or aryls, in addition to mineral materials such as silica and the combinations thereof. The bond Ro between the entity Sil and the entity B is obtained by means of “click chemistry” and corresponds to formula (II.1) or (II.2), Z representing a carbon atom or a nitrogen atom.

  • Publication number: 20090160095
    Abstract: The disclosure relates to a starch-polyester graft copolymer, for example formed by the reactive blending of a thermoplastic starch (TpS) and/or a modified thermoplastic starch (MTpS) with a biodegradable polyester. The thermoplastic starch includes starch (e.g., a high-amylose starch) and a plasticizer, and can further include a chemical modifier and an optional initiator. The graft copolymer preferably is completely (or substantially completely) biodegradable, for example based on the biodegradability of each of its components. The graft copolymer can be formed into sheets of material that can be subsequently thermoformed, for example into single-use, disposable articles.
