Hydrophilically-Modified Polyisocyanate Zhang Faai, Wang Yunpu*, Chai Chunpeng (Institute of Polymer , Northwest Normal University, Lanzhou 730070) Abstract Three main methods of preparing hydrophilically-modified polyisocyanate were introduced, that is, modified with nonionic type monoether poly(ethylene glycol), modified with ionic type compounds containing hydroxyl and ionic groups, and modified with above two methods together. Some factors affecting the modification of polyisocyanate were discussed.
