ABSTRACT:
The present invention relates to novel fire retardant compositions, based on the compounds 2-bromomethyl-2-hydroxy-methylpropane-1,3-diol, 2,2-bis(bromomethyl)propane-1,3-diol, 2-bromomethyl-2-hydroxymethyl-1,3-dibromopropane, and mixtures thereof, the compositions having a general formula (BrCH.sub.2).sub.m C[CH.sub.2 O(CH.sub.2 O).sub.x H].sub.4-m wherein m is between 1.6 to 2.3 and x is between 0.75 to 1.10. These compositions are characterized by their particular infra-red spectra.
The novel fire retardant compositions are produced by the reaction of formaldehyde or its polymeric forms with the above compounds, followed by the removal of water from the reaction system.
The fire retardant compositions according to the present invention are suitable as active or additive fire retardant ingredients for various polymeric materials, such as polyurethane, polyester or epoxide resins.
