A barrier film composition can comprise a thermoplastic web comprising a thermoplastic polymer and a dispersed cyclodextrin composition having substituents that compatibilize the cyclodextrin in the film. The thermoplastic / cyclodextrin film obtains substantial barrier properties from the interaction between the substituted cyclodextrin in the film material with a permeant. The substituents on the cyclodextrin molecule causes the cyclodextrin to be dispersible and stable in the film material resulting in an extrudable thermoplastic. Such materials can be used as a single layer film material, a multilayer film material which can be coated or uncoated and can be used in structural materials wherein the thermoplastic is of substantial thickness resulting in structural stiffness. The cooperation between the cyclodextrin and the thermoplastic polymer provides barrier properties to a web wherein a permeant can be complexed or entrapped by the cyclodextrin compound and held within the film preventing the permeant from passing through the film into the interior of a film, an enclosure or container. The permeant can comprise a variety of well known materials such as moisture, aliphatic or aromatic hydrocarbons, monomer materials, off flavors, toxic compounds etc.

The phenoxyphosphazene compound of the present invention is prepared by treating a phenoxyphosphazene compound with (a) at least one adsorbent selected from activated carbon, silica gel, activated alumina, activated clay, synthetic zeolite and macromolecular adsorbents, (b) at least one reagent selected from metal hydrides, hydrazine, hypochlorites, thiosulfates, dialkyl sulfuric acids, ortho esters, diazoalkanes, lactones, alkanesultones, epoxy compounds and hydrogen peroxide or (c) both the adsorbent and reagent. Incorporation of the phenoxyphosphazene compound prepared by the process of the invention into a synthetic resin achives the following advantages: the synthetic resin can be prevented from discoloration; when the resultant resin composition is stored for a long time, the properties of the synthetic resin, such as heat resistance, weatherability, resistance to discoloration and chemical resistance are not deteriorated; and the resin composition gives a resin composition molded article excellent in properties such as flame retardancy, thermal stability, and moldability.

The present invention provides a monolithic silicone in the form of an aerogel or a xerogel having flexibility and capable of dissolving molecules of a substance. This silicone monolithic body having continuous through passages is synthesized by copolymerizing starting materials of both a bifunctional alkoxysilane and a trifunctional alkoxysilane or tri- or higher functional alkoxysilanes through a sol-gel reaction for forming a Si—O network while causing phase separation.

This invention relates to aliphatic polyesters having a controlled thermal decomposition, hydrolizability, and biodegradability, in which OH terminals and COOH terminals are decreased through a ring-opening polymerization of a lactone and lactide by a mono alcohol or a metal alkoxide, or by decreasing both terminals through combining polymer terminals with diisocyanate. From a composition containing the polyesters, this invention provides a controlled release composition for agriculture. From a resin primarily containing fatty acid cellulose ester derivatives, this invention provides a base film for a marking film without volatilization and plasticizer migration problems; a picture image formable heat-sensitive transfer recording material with excellent strippability, coloring concentration, and brightness; a conductive coating composition with excellent storage stability, adhesion, and conductivity; a single-liquid type coating for a moisture-curable graft copolymer, and a non-toxic and non-irritating coating composition with excellent dryability. The copolymers of this invention also have excellent heat and impact resistance.

A process for preparing a hyperbranched polymer having a weight-average molar mass of at least 30,000, includes coupling a first prepolymer having at least three functional end groups with a second prepolymer having at least two functional end groups by a dehydration condensation reaction between the end groups in the prepolymers. The number of arms and / or molar mass of the functionalized prepolymers can accurately be adjusted, thus affecting the properties of the resulting hyperbranched polymer in a desired way. The polymer can be equipped e.g. with hydrophobic and hydrophilic parts. Also, the number of functional end groups, that optionally can be used for further chemical reactions, in the hyperbranched polymer can easily be adjusted to a desired level. The hyperbranched high molar mass polymer can be prepared in high yields without the use of organic solvents or linking compounds, which is advantageous from an environmental as well as an economical point of view.

A method for producing a low oxygen content activated carbon material includes heating a natural, non-lignocellulosic carbon precursor in an inert or reducing atmosphere to form a first carbon material, mixing the first carbon material with an inorganic compound to form an aqueous mixture, heating the aqueous mixture in an inert or reducing atmosphere to incorporate the inorganic compound into the first carbon material, removing the inorganic compound from the first carbon material to produce a second carbon material, and heating the second carbon material in an inert or reducing atmosphere to form the low oxygen content activated carbon material. The activated carbon material is suitable to form improved carbon-based electrodes for use in high energy density devices.
