Abstract
An adhesive composition which contains two distinct polyurethane prepolymers and a halogenated polyolefin and which is useful for bonding flock fibers to a thermoplastic or an elastomeric substrate. The first polyurethane prepolymer is derived from poly(alkylene oxide) polyols while the second polyurethane prepolymer is derived from poly(alkylene oxide) polyols and a dimer acid polyol. Both of the polyurethane prepolymers are preferably derived from a mixture of poly(alkylene oxide) polyols having different molecular weights.
