Abstract
Abstract This invention relates to an adhesive composition useful for backsizing tufted carpets. The composition contains a copolymer of ethylene, a wax, and a particular resin extender blend and can be applied as a hot melt to the backside of a carpet. The composition has excellent adhesion characteristics as well as toughness, high softening point, and a suitable viscosity at coating application temperatures. Fillers can also be included in the composition as well as other ingredients.
