Abstract
Hot melt adhesive compositions combining the characteristics of thermoplastic hot melt adhesives and reactive adhesives can be prepared by blending a polyester polyether thermoplastic elastomer having the formula ##STR1## wherein Nu is a predominately cyclic nucleus and R.sub.1 is randomly selected from either a C.sub.2-6 alkylene or an amorphous polyether subunit comprising a polyoxyalkylene group with a polyisocyanate prepolymer. The resulting composition is flexible and may be used as an adhesive or as a sealant.
