The gas barrier resin composition includes: a polymer (A) whose repeating unit contains a functional group with active hydrogen and/or a polar functional group with hetero atom; and an organic compound (B) containing, in its molecule, a functional group with active hydrogen and/or a polar functional group with hetero atom. The gas barrier film includes the gas barrier resin composition.

Abstract: The present invention provides new process for preparing inorganic fine particles, which suppresses agglomeration and adhesion of particles due to heat when preparing powder from a raw material liquid such as a slurry of zirconia hydrate fine particles in order to obtain inorganic raw material powder having sharp particle size distribution. Furthermore, the present invention provides a new process for preparing inorganic fine particles, which can make the chemical structure homogenous among the produced particles and inside the particles even in a multi-component system. The present invention provides a process for preparing inorganic fine particles, which comprises heating and applying impulse waves to a raw material liquid.

Abstract: The present invention provides a modified substrate including a hydrophilic polymer wherein the soluble hydrophilic polymer ratio is 15 weight percent or less and the number of adhered human blood platelets is 10/4.3×103 ?m2 or less. In addition, the present invention provides a method for producing a modified substrate including a step of irradiating the substrate with radiation while the substrate is brought into contact with an aqueous solution containing a hydrophilic polymer and an antioxidant. The present invention provides a modified substrate having high hematologic compatibility wherein the hydrophilic polymer is immobilized on the surface of the substrate, and a method for producing the same.
