Abstract:
A process for preparing a hot melt adhesive composition, the process comprising the steps ofproviding at, least one non-thermoplastic hydrocarbon elastomer in a compounding device; compounding at least one thermoplastic additive with the non-thermoplastic hydrocarbon elastomer to form a blend of the at least one non-thermoplastic hydrocarbon elastomer and the 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 the melt viscosities are measured at a shear rate of 100 secondsâˆ’1 at a processing temperature between about 80Â° C. and about 200Â° C.
