Poyurea based dispersions, foams prepared therefrom, and a process for the preparation therein

摘要

Stable urea group-containing dispersions are obtained in situ by reacting carbon dioxide with an amine in the presence of a continuous phase carrier. These amine/carbon dioxide condensation adducts dispersed in the carrier are employed in the formation of polyurethane foams, polyurethane elastomers and coatings, and polyurethane microcellular foams.
