ABSTRACT:
Isocyanate compositions are disclosed which yield aqueous emulsions on admixture with water. The emulsions are sufficiently stable to permit employment as particle board binders and like uses. The compositions of the invention are derived by reaction of a polymethylene polyphenyl polyisocyanate with a particular group of polyethylene glycols which have been capped with a block of propylene oxide residues.
