Abstract
It has been discovered that amorphous polybutene copolymers that have a softening point of from about 70 to about 105° C. and viscosity of less than about 1,900 cP at 190° C. possesses desirable properties and may be used to make a low application temperature hot melt adhesive for disposable absorbent articles.
