US Patent:

40038645, Jan 18, 1977

Filed:

Jul 2, 1976

Appl. No.:

5/702152

Inventors:

Shirley H. Roth - Highland Park NJ
William S. Stoy - Princeton NJ

Assignee:

Cities Service Company - Tulsa OK

International Classification:

C08J 902

US Classification:

260 25FP

Abstract:

Intumescent amine-aldehyde copolymer compositions having improved UV stability are obtained by incorporating about 0. 5-75% by weight of a polyol polyacrylate or polyol polymethacrylate into an intumescent composition comprising a low molecular weight, water-insoluble amine-aldehyde copolymer consisting essentially of repeating units which correspond to the formula: wherein Q is the residue of an alkanal containing 1-5 carbon atoms and R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, halo, nitro, acetamido, or sulfonamido. The preferred compositions are those in which the amine-aldehyde copolymer is a sulfanilamide-formaldehyde copolymer and the polyol ester is a liquid ester.

Appl. No.:

5/664738

Inventors:

Shirley H. Roth - Highland Park NJ

Assignee:

Cities Service Company - Tulsa OK

International Classification:

C08G 1208
C08J 902

US Classification:

260 25F

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.

US Classification:

260 25FP

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 10-50% by weight of a synergist corresponding to the formula: ##SPC2## Wherein X is chloro or bromo, T is halo, hydrogen, or a hydrocarbyl or hydrocarbyloxy group, and Z is a monocyclic divalent saturated polybromocycloalkylene group containing 5-16 carbon atoms and 2-6 bromine atoms: said valences being on adjacent carbon atoms; 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.
