A vessel for aerosol is manufactured by a high-nitryl resin which is formed by graft polymerizing a mixture of monomers of a 60 to 90 weight part comprising an unsaturated nitryl compound of at least 60 weight % and an aromatic vinyl compound of at least 5 weight % to diene synthetic rubber of a 1 to 40 weight part containing a conjugated diene monomer of 50 weight % or more, wherein assuming that a content of the unsaturated nitryl compound in the resin grafted to the rubber is set to X weight % in the high-nitryl resin and a content of the unsaturated nitryl compound in the matrix resin is set to Y weight %, the vessel is manufactured by the resin which satisfies the relation of 60<X<Y<90 between X and Y.
A vessel for aerosol comprising a high-nitrile resin blend, said vessel capable of storing ethyl alcohol, wherein said high-nitrile resin blend comprises a polymer having from 60 to 90 weight parts of a mixture of monomers comprising at least 60 weight % of an unsaturated nitrile compound and at least above 5 weight % of an aromatic vinyl compound which has been graft polymerized to 1 to 40 weight parts of diene synthetic rubbers containing 50 weight % or more of a conjugated diene monomer, wherein said high-nitrile resin comprises a grafted resin blend and a non-grafted resin wherein the content of unsaturated nitrile compound in resin grafted to the diene synthetic rubbers in the polymer is represented by X weight % and the content of unsaturated nitrile compound in the non-grafted resin is represented by Y weight %, the vessel for aerosol comprising a high-nitrile resin blend which satisfies a relation of
