THERMOPLASTIC ADDITIVES FOR HOT MELT ADHESIVES BASED ON NON-THERMOPLASTIC HYDROCARBON ELASTOMERS

摘要

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.
