Reactive hot-melt adhesive composition.

摘要

A reactive hot-melt adhesive composition comprises at least one urethane prepolymer and a thermoplastic elastomer, and as a polyol for the urethane prepolymer a polyether polyol having an oxyalkylene group having a carbon number of six or more is used, by which the compatibility of the urethane prepolymer and the thermoplastic elastomer is improved so as to provide an adhesive composition excellent in stability and adhesive strength.
