ABSTRACT:
The instant invention is directed to novel modified polyisocyanates which contain sulphonic acid ester groups and to the method of manufacture thereof. The polyisocyanates of the instant invention are produced by reacting isocyanatoaryl sulphonic acids with oxiranes and/or oxetanes. The resultant products are highly useful in the production of polyurethane resins.
