PHOSPHORIC ESTER
Phosphate esters (I), obtd. by (a) reacting a mono-, oligo-or polyamine with an alkylene oxide (AO) or alkylene carbonate to give an aminoalcohol or an amino-mono-, -oligo- or -polyetheralcohol (A) in which 50-100% of the alkoxylatable NH gps. in the amine are alkoxylated, (b) reacting (A) with a hy...

Zusammenfassung: | Phosphate esters (I), obtd. by (a) reacting a mono-, oligo-or polyamine with an alkylene oxide (AO) or alkylene carbonate to give an aminoalcohol or an amino-mono-, -oligo- or -polyetheralcohol (A) in which 50-100% of the alkoxylatable NH gps. in the amine are alkoxylated, (b) reacting (A) with a hydroxycarboxylic or dicarboxylic acid and a diol to give a mono-, oligo- or polyester (B1), or with a di-isocyanate and a diol to give a di-, oligo- or poly-urethane (B2), in which 50-100% of the terminal OH gps in (A) are esterified or converted into urethane gps., and (c) reacting (B1) or (B2) with an ester- forming phosphorus cpd. (PC) so that 5-100% of the terminal OH gps. in (B1/2) are converted into phosphate ester gps. and the P atoms are mono- and/or di- and opt. triesterified. Also claimed is the above process for the prodn. of (I). |
