TH6528A - Adhesive resin components and their applications in sheet metal fabrication? - Google Patents

Abstract

According to this invention, the adhesive resin is defined as consisting of (a) an ethylene/alpha-olefin copolymer with a density of 0.850–0.900 g/cm³ in a quantity of 90–50% by weight and containing 75–95 mol% ethylene; (b) an ethylene and radically polymerizable radical copolymer in a quantity of 5–50% by weight, in which the radically polymerizable radical copolymer contains 5–40% by weight; and (c) 1.0–30 parts by weight of graft-modified polyethylene, relative to 100 parts by weight of the sum of (a) and (b) as described above, where part or all of the said polyethylene has been graft-modified with unsaturated carboxylic acid or its derivatives. And stacked sheets that use this resin adhesive component.
