Composite body comprises at least two styrene polymer foam plates and an optionally crosslinked hot melt adhesive composition present between the styrene polymer foam plates, comprising at least one thermoplastic, silane grafted poly-alpha -olefin that is solid at 25[deg] C. The hot melt adhesive composition is optionally subsequently crosslinked. An independent claim is also included for bonding at least two styrene polymer foam plates, comprising (i) melting the hot melt adhesive composition and/or converting the hot melt adhesive composition into a flowable state, containing at least one silane grafted poly-alpha -olefin that is solid at 25[deg] C, (ii) applying the molten hot melt adhesive composition on a first styrene polymer foam plate, (iii) contacting the molten hot melt adhesive composition with a second styrene polymer foam plate, on the side facing away from the first plate, (iv) optionally cooling and curing the molten hot melt adhesive composition, where the application amount of the molten hot melt adhesive composition is 40-250 g/m 2>, preferably 80-150 g/m 2>. |
