Modified polyether polyol for preparation of polyurethane polymer |
摘要 |
A modified polyether polyol for use in the manufacture of polyurethane polymer having improved fire-resisting qualities, and the method for making such a polyether polyol. The modified polyether polyol includes a polyether polyol having urea chemically bound thereto. The method for making the modified polyether polyol includes reacting a reducing sugar with propylene oxide to produce a polyether polyol, which is then reacted with unsubstituted urea to chemically bind the urea thereto to produce a modified polyether polyol.
