Abstract
Official abstract text for this publication.
An adhesive for polyolefin used for an extrusion-formed multilayered structure that includes, at least, a propylene type resin layer and an ethylene type resin layer, the adhesive for polyolefin comprising an olefin resin that has methyl branches at a ratio of 10 to 200 per 1000 carbon atoms on a main chain thereof.
First claim
Opening claim text (preview).
1 . An adhesive for polyolefin used for an extrusion-formed multilayered structure that includes, at least, a propylene type resin layer and an ethylene type resin layer, said adhesive for polyolefin comprising an olefin resin that has methyl branches at a ratio of 10 to 200 per 1000 carbon atoms on a main chain thereof. 2 . The adhesive for polyolefin according to claim 1 , wherein said olefin resin has methyl branches at a ratio of 12 to 200 per 1000 carbon atoms on a main chain thereof. 3 . The adhesive for polyolefin according to claim 1 , wherein said olefin resin has been modified with an acid. 4 . A multilayered structure that includes a propylene type resin layer and an ethylene type resin layer, wherein an intermediate layer comprising the adhesive for polyolefin described in claim 1 is provided between said propylene type resin layer and said ethylene type resin layer. 5 . The multilayered structure according to claim 4 , wherein the intermediate layer comprising said adhesive for polyolefin is provided adjoining said propylene type resin layer and said ethylene type resin layer. 6 . The multilayered structure according to claim 4 , wherein said adhesive for polyolefin has been modified with an acid and, further, includes a gas-barrier layer as an intermediate layer. 7 . The multilayered structure according to claim 4 , wherein the intermediate layer comprising said adhesive for polyolefin is provided between said propylene type resin layer and the gas-barrier layer, and between said ethylene type resin layer and the gas-barrier layer. 8 . The multilayered structure according to claim 4 , wherein the multilayered structure is used as a directly blow-formed container.
