| Abstract: | Abstract New phosphorus - containing monomers and oligomers from tetrakis(hydroxymetyl)phosphonium chloride and dialkylphosphites are synthesized. On the basis of new products phosphorus-containing polyesters, polyurethanes and polyuretanesemicazbazides with improved fire resistance are obtained. The dependence of fire resistance of the polymers on the structure of the use flame retardants is investigated. |
