Title
(EN) HOT MELT ADHESIVE COMPOSITION
(FR) COMPOSITION ADHÉSIVE THERMOFUSIBLE
(JA) ホットメルト粘接着剤組成物
Abstract
(EN)
The present invention provides a hot melt adhesive composition which contains a modified hydrocarbon resin and a thermoplastic elastomer, and which is configured such that: the modified hydrocarbon resin is obtained by introducing a carboxyl group or an acid anhydride group derived from an unsaturated carboxylic acid or an unsaturated dicarboxylic acid anhydride into a resin that is obtained by hydrogenating a hydrocarbon resin that contains 20-70% by mass of a 1, 3-pentadiene monomer unit, 10-50% by mass of an alicyclic monoolefin monomer unit having 4-6 carbon atoms, 5-40% by mass of an acyclic monoolefin monomer unit having 4-8 carbon atoms, 0-1% by mass of an alicyclic diolefin monomer unit and 0-40% by mass of an aromatic monoolefin monomer unit; and the modified hydrocarbon resin has an iodine number within the range of 45-125 gI2/100 g.
