ABSTRACT:
A water-insoluble amine-aldehyde copolymer intumescent agent having a number average molecular weight of about 350-2000 and consisting essentially of repeating units corresponding to the formula: ##SPC1##
Wherein Q is the aldehyde residue and R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, halo, nitro, acetamido, or sulfonamido is mixed with about 10-100% by weight of 1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane as a synergist to increase the foam volume obtainable from the intumescent agent. The compositions comprising the intumescent agent and synergist may be applied to substrates by conventional techniques.
