Phosphorus-containing polyurethanes are synthesized by reacting phosphorus-containing diisocyanates, bis(4-isocyanatophenoxy) phenyl phosphine oxide (BIPPO) and bis(3-isocyanatophenyl)phenyl phosphine oxide (BIPPPO), with various diols. The chemical structures of the obtained monomers and polymers a
A mixture of 12.5 g of 2,2-dimethyl-l,3-dioxolan and 25 ml of glacial acetic acid is added to 10 grams of addition product (3). The mixture is then stirred and heated to 60°C. The diazonium salt dissolves, and after 10 minutes, the reaction is completed. After working up as described above, 89.3 % o
