Abstract
A hot-melt adjuvant-free formulation includes a butene-1-co-hexene-1 copolymer formed from butene-1 and hexene-1 monomers with a supported Ziegler-Natta catalyst, a styrenic block copolymer with less than 15 percent styrene, a high melt flow index metallocene, a high melt flow rate polypropylene with a melt flow above 18000 cps, and a low molecular weight polyethylene wax, wherein the molecular weight is less than 1000 centipoise at a temperature of 350 degrees Fahrenheit.
