ADHESIVE AGENT COMPRISING ETHYLENE-( -OLEFIN) COPOLYMER
An adhesive with improved heat stability is provided. The adhesive includes an ethylene·±-olefin copolymer (A) having a number-average molecular weight of 5000 to 100000 in terms of polystyrene as measured by gel permeation chromatography and a density of 860 to 970 kg/m 3 , wherein in the ethylene·±-olefin copolymer (A), the total number of vinyl-type double bond, vinylidene-type double bond, 2-substituted olefin-type double bond and 3-substituted olefin-type double bond is less than 0.5 per 1000 carbon atoms as measured by 1 H-NMR.
