Abstract
The method is used in the utilization of waste productsproduced as a result of the production and utilization of solidand elastic foam polyurethanes and polyurethane elastomers. By it,phosphorus-containing oligomers are produced which can be used forthe synthesis of solid foam polyurethanes and as additives topolymers improving the compatibility, the adhesion, the combustionstability, the frost resistance and some physicomechanicalcharacteristics, as well as for the synthesis of phosphorus- andmetal-containing additives for polymers improving their resistanceagainst UV irradiation. By the method the waste products aretreated with esters (di- and mono-) of the phosphonic acid withthe general formulawhere R means alkyl or halogenalkyl, X is alkyl or halogenalkyl orH, Y is H or alkyl, or with esters (tri- and di-) of thephosphoric acid with the general formulawhere R means alkyl or halogenalkyl, X is alkyl or halogenalkyl orH, at temperatures from 140 to 200°C.1 claim
