摘要:
A blocked hydrophilic polyurethane with molecular weight of 500.about.40,000, 5.about.70% solid content and 5.about.200 milliequivalent per 100 g polymer of sulfonic acid salt, can be prepared from following reactants:a. Organic isocyanates;b. Polyols, including polyether polyol, polyester polyol, polycarbonate, and polycaprolactone, that can participate in the polyaddition reactions with isocyanates.c. Polyols containing sulfonate group.d. Organic blocking agents capable of reacting with isocyanates.The blocked hydrophilic PU resins formed from above reactants can be applied for the anti-wrinkle treatment of cellulosic textiles with excellent performance.
