摘要:
A laminated article which comprises a layer (A) of a saponified ethylene - vinyl acetate copolymer resin having an ethylene content of 20 - 55 % by mole and a degree of saponification of not less than 90 % by mole; laminated with a layer (B) of a hydrophobic thermoplastic resin; through the medium of a layer (C) of an adhesive resin; said adhesive resin contains a polymer (X) comprising ethylene component - vinyl acetate component - ethylenically unsaturated carboxylic acid component or anhydride thereof - styrene type vinyl compound component, and a copolymer (Y) comprising ethylene component - vinyl acetate component, in an amount satisfying specific formulae, and the process for production thereof, which has a remarkably excellent adhesion between layers, as well as excellent mechanical characteristics and gas barrier properties, and is adapted to a container for foods and packaging material.
摘要:
Disclosed are a colorless and transparent carboxyl-modified resin of saponified ethylene-vinyl acetate copolymers prepared from an ethylene-vinyl acetate copolymer, the 1.0 mm-thick sheet therefrom having a total transmittance of more than 90%, a haze of less than 3% and a yellowness index of 3 and the preparation of the resin. The uses of the resin are also disclosed for laminated glass wherein the resin is used as an interlayer as well as for a solar cell module wherein the resin is used as a sealing material of a semiconductor element.

摘要:
A heat adherable resin composition which comprises (a) a carboxyl-modified resin obtained by the reaction of a partially saponified product of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 10 to 55 weight percent with an unsaturated carboxylic acid or dicarboxylic acid anhydride and (b) a monoolefin-unsaturated carboxylic acid copolymer or metal salt thereof is valuable as an adhesive layer for the heat sealable sheet made of aluminum foil which is used in the food industry in sealing and packaging the mouths of glass containers.

摘要:
Disclosed is an adhesive for bonding an ethylene/vinyl alcohol copolymer and polystyrene, which comprises a modified ethylene/vinyl acetate copolymer obtained by graft-copolymerizing a styrenic vinyl monomer and an α,β-unsaturated carboxylic acid to an ethylene/vinyl acetate copolymer. A laminated article having the said adhesive as an interlayer and production thereof are also disclosed. The laminated article shows strong resistance to delamination and excels in processability. Therefore, the laminate is valuable as a deep-draw forming material with enhanced gas barrier properties for a preservation rigid container for foods.
