Abstract

A hot melt adhesive (HMA) composition comprises: a) an ethylene/alpha-olefin multi-block interpolymer that has a melt viscosity (177° C.)≤50,000 mPa·s; b) an anhydride and/or carboxylic acid functionalized propylene-based polymer that has a melt viscosity (190° C.)≤50,000 mPa·s; c) a tackifier; and d) a wax. Such composition delivers both a high temperature heat resistance and a fast set time.
