| titleOfInvention | Heat-activatable polyurethane/urea adhesive in aqueous dispersion |
| abstract | A stable colloidal aqueous dispersion of a partially and homogeneously crosslinked polyurethane/polyurea is made by inserting an integral emulsifier and an internal dispersion stabilizer into a polyurethane having a polyester- or polycaprolactone diol backbone and chain extending and crosslinking it with a mixture of diamine and triamine having a functionality of from 2.05 to 2.18. A highly concentrated solution of a dihydroxycarboxylic acid in a solvent such as N-methyl pyrrolidone permits the hydroxyl groups to react thoroughly and quickly with an isocyanate-terminated polyurethane and, consequently, a minimal amount of the solvent is present in the adhesive after water is removed from the aqueous dispersion. The adhesive is thus heat resistant at 70 DEG C despite its relatively small degree of crosslinking. |
