Barrier material comprising a thermoplastic and a compatible cyclodextrin derivative

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.

Aliphatic copolyester resin, a preparation method, an aliphatic polyester resin composition, uses thereof, a coating composition, a particle-state composition for agriculture and gardening coated by degradabel layer

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.
