Abstract
This invention claims hot melt adhesive compositions that can be used to form elastic composites that are useful in disposable absorbent articles. The compositions have good elastic recovery and high peel adhesion at a viscosity of less than about 20,000 cps at 177° C. The low viscosity makes it possible to apply the adhesive at a high line speed and target application to only those areas requiring elastic performance.
