  • Carbamate-phosphonates as flame-proofing agents in polyurethane foam
    Patent number: 4113671
    Abstract: Carbamates of diethyl methylphosphonate of the formula: ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, are linear or branched alkyl or hydroxyalkyl radicals containing 2 or 3 carbon atoms, or R.sub.1 and R.sub.2 together with the nitrogen atom to which they are attached form a ring containing 4 or 5 carbon atoms, or R.sub.1 is phenyl and R.sub.2 is hydrogen, may be prepared by reacting diethyl hydroxymethyl-phosphonate chloroformate with an amine, and find application in flameproofing rigid or flexible polyurethane foams.
    Type: Grant
    Filed: October 3, 1977
    Date of Patent: September 12, 1978
    Assignee: Societe Nationale des Poudres et Explosifs
    Inventors: Serge L. Lecolier, Jean-Marie J. Biehler
  • Flame resistance of foams using diethyl hydroxymethylphosphonate esters
    Patent number: 4101472
    Abstract: Novel diesters of diethyl hydroxymethylphosphonate of the formula: ##STR1## in which R.sub.1 and R.sub.4 are alkylene radicals --(CH.sub.2).sub.m -- in which m is 0 or an integer; R.sub.2 and R.sub.3 are H or alkyl radicals, the total number of carbon atoms in R.sub.1, R.sub.2, R.sub.3 and R.sub.4 being not more than 10, are described.These diesters are valuable flameproofing agents for rigid and flexible polyurethane foams and for thermoplastic polyolefin and polyester foams.
