摘要： The present invention relates to a hot melt composition, which is suitable as a dampening, preferably a sound deadening, composition comprising, i) at least one poly-α-olefin; ii) at least one elastomeric styrene based copolymer; iii) at least one thermoplastic polymer having a melt index of 50 to 5000 at 190℃/2.16 kg selected from ethylene vinyl acetate (EVA), ethylene acrylic acid (EAA), alkyl acrylates, alkyl methylacrylates (EMA), ethylene 2-ethyl hexyl acrylate (EEHA) or combinations thereof; and optionally iv) at least one additive, preferably selected from fillers; stabilizers; colorants; pigments; waxes; polymers which are different from i) to iii); moisture scavengers; or combinations thereof. Furthermore, the present invention relates to a dampening, preferably a sound deadening, article comprising the hot melt composition of the present invention and the use of the hot melt composition of the present invention in dampening, preferably sound deadening.

摘要： The present invention relates to a hot melt composition, which is suitable as a damping, preferably a sound deadening, composition comprising i) at least one poly-α-olefin; ii) at least one elastomeric styrene based copolymer; iii) at least one tackifier; iv) at least one macrocycle; and optionally v) at least one additive, preferably selected from fillers; stabilizers; colorants; pigments; waxes; thermoplastic compounds having a melt index of 600 to 5000 at 190℃/2.16 kg (ASTM D1238) selected from ethylene vinyl acetate (EVA), ethylene acrylic acid (EAA), alkyl acrylates, alkyl methylacrylates (EMA), ethylene 2-ethyl hexyl acrylate (EEHA) polymers or combinations thereof; moisture scavengers; or combinations thereof. Furthermore, the present invention relates to a dampening, preferably a sound deadening, article comprising the hot melt composition of the present invention and the use of the hot melt composition of the present invention in dampening, preferably sound deadening.
