Gas barrier resin composition and process for producing the same

摘要

A resin composition comprising 100 parts by weight of an aggregated inorganic layer compound and 200-10,000 parts by weight of a resin, the particle size of the aggregated inorganic layer compound satisfying the mathematical expressions (1): $wherein\; L\; is\; the\; average\; particle\; diameter\; of\; the\; inorganic\; layer\; compound\; before\; aggregation\; and\; D\; is\; the\; average\; particle\; diameter\; of\; the\; inorganic\; layer\; compound\; after\; aggregation\; (average\; aggregated\; particle\; diameter),\; and\; a\; process\; for\; producing\; the\; resin\; composition\; described\; above\; which\; comprises\; a\; process\; of\; dispersing\; the\; inorganic\; layer\; compound\; in\; a\; dispersion\; medium\; to\; obtain\; a\; liquid\; dispersion\; of\; the\; inorganic\; layer\; compound,\; a\; process\; of\; aggregating\; the\; inorganic\; layer\; compound\; present\; in\; the\; liquid\; dispersion\; obtained\; by\; process\; 1,\; and\; a\; process\; of\; compounding\; the\; liquid\; dispersion\; of\; the\; inorganic\; layer\; compound\; aggregated\; by\; process\; 2\; with\; the\; resin.\; The\; resin\; composition\; of\; the\; present\; invention\; is\; excellent\; in\; gas\; barrier\; property,\; particularly\; in\; oxygen\; barrier\; property.$
