HYDROCARBON TACKIFIERS FOR ADHESIVE COMPOSITIONS

摘要

The present invention is related to an adhesive composition comprising a 50-95 wt% polymer blend and a tackifier. The blend has a first and second propylene-based polymer, both different homopolymers of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin. The blend has a melt viscosity, measured at 190°C, of 1,000 to 30,000 cP. The tackifier has a softening point of 95°C to 115°C, an aromaticity of 3 mol% to 10 mol% aromatic protons, and a Cloud Point of 40°C to 65°C.
