The reactive moisture cure hot melt adhesives of the invention have substantially improved assembly properties as a result of the unique combination of materials that provide excellent green strength. The adhesive includes at least an isocyanate compound, a polyether polyol, an aromatic tackifying composition, a thermoplastic polymer, and a block polymer having at least an A block and at least a B block, wherein the A block comprises a crystalline or semi-crystalline block and the B block comprises a rubbery or amorphous block. Such block polymers can have linear, branched, radial, or dendritic morphologies. |
