The invention is directed toward a hot melt adhesive composition and processes for producing the same. The hot melt adhesive composition comprises: at least one non-thermoplastic hydrocarbon elastomer; at least one thermoplastic additive, wherein a ratio of melt viscosity of the at least one thermoplastic additive to melt viscosity of the at least one non-thermoplastic hydrocarbon elastomer is less than about 1:20 when measured at a shear rate of 100 seconds- 1 at a particular hot melt processing temperature; and at least one modifier.
La présente invention concerne une composition d'adhésif thermofusible et des processus de production de cette composition. Cette composition d'adhésif thermofusible comprend: au moins un élastomère hydrocarbure non thermoplastique, au moins un additif thermoplastique, le rapport de la viscosité à l'état fusion de cet additif thermoplastique sur la viscosité à l'état fusion de cet élastomère hydrocarbure non thermoplastique étant inférieur à environ 1:20 mesuré à un taux de cisaillement de 100 secondes-1 et à une température de traitement de fusion, et au moins un modificateur.
