Abstract
Abstract Disclosed herein is a resin composition obtained by mixing an olefin-base resin, which has in turn been obtained by partially neutralizing a free carboxyl group in a random copolymer of an α-olefin and an α,β-ethylenically-unsaturated monocarboxylic or dicarboxylic acid, with a volatile rust preventive in a specific amount or more. The resin composition has excellent rust preventive properties and can hence be used advantageously as a wrapping material for metal products.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A rust preventive resin composition suitable for use in wrapping material, comprising: an olefin-base resin obtained by partially neutralizing a free carboxyl group in a random copolymer of an α-olefin and an α,β-ethylenically-unsaturated monocarboxylic or dicarboxylic acid, the latter being contained in an amount of 1.0-2.0 mole %, with ions of an alkali metal or alkaline earth metal having a normal electrode potential lower than aluminum to a level in a range of 5-90 mole% based on the original content of the free carboxyl group; and a votive rust preventive selected from one or more amine salt compounds in an amount of at least 0.5 parts by weight per 100 parts by weight of the olefin-base resin.
Claim 2
Dependent Claim
117 words
A rust preventive resin composition suitable for use in wrapping material, comprising: an olefin-base resin obtained by partially neutralizing a free carboxyl group in a random copolymer of an α-olefin and an α,β-ethylenically-unsaturated monocarboxylic or dicarboxylic acid, the latter being contained in an amount of 1.0-2.0 mole %, with ions of an alkali metal or alkaline earth metal having a normal electrode potential lower than aluminum to a level in a range of 5-90 mole% based on the original content of the free carboxyl group; and a votive rust preventive selected from one or more amine salt compounds in an amount of at least 0.5 parts by weight per 100 parts by weight of the olefin-base resin.
