Abstract
The amino-aldehyde-phosphate resins and copolymers are produced by reacting an amino compound, an aldehyde and a phosphorus oxyacid. These components may be reacted at ambient or elevated temperature or at ambient, elevated or reduced pressure, They may be produced in the form of water based pre-polymer, a clear resin or as granules or powder. These resins are flame retardant and may be added to or applied on to flammable organic materials to make them flame retardant. The amino-aldehyde-phosphate resins and copolymers may be utilized as coating agent, as an adhesive, films, laminates and as flame retardant compounds.

- A) amino compound;
- B) aldehyde;
- C) phosphorus oxyacid;
- D) organic compound that will react with component A, B, and/or C, in the amount of 0 to 100 percent, percentage based on the weight of amino compound;
- E) filler, in the amount of 0 to 200 percent, percentage based on the weight of amino compound;
- F) water, in the amount of 0 to 200 percent, percentage based on the weight of amino compound;
- G) acid and/or basic compound to adjust the pH, in the amount 0 to 10 percent, percentage based on the weight of amino compound;
- component (A) and (D) are mixed or reacted then component (F) is added, then component (C) is mixed and/or reacted with component (A) and (D) or (B) and/or (A) and (B) in a molar ratio of amino with or without organic compound:aldehyde:phosphorus oxyacid of 1-2:1-2:0.5-1 then component (E) is added and mixed, then the components are mixed and reacted at ambient to 90 degrees C. and at ambient to reduced pressure, then component (G) is added to adjust the pH.
An amino-aldehyde-phosphate resin produced by the process consisting of mixing, heating and reacting the following components:
- A) amino compound
- B) aqueous aldehyde
- C) phosphorus oxyacid
- Component C is first added and reacted with component B then component A is added at ambient temperature and pressure, mixed and reacted at ambient or elevated temperature in a molar ratio of amino compound:aldehyde:phosphorus oxyacid of 1-2:1-2:0.5-1.

- A) amino compound;
- B) aldehyde;
- C) phosphorus oxyacid;
- D) organic compound that will react with component A, B, and/or C, in the amount of 0 to 100 percent, percentage based on weight of the amino compound;
- E) filler, in the amount of 0 to 200 percent, percentage based on the weight of amino compound;
- F) water, in the amount of 0 to 200 percent, percentage based on the weight of amino compound;
- G) acid and/or basic compound, in the amount of 0 to 10 percent, percentage based on weight of the amino compound to adjust the pH;
- component (A) and (D) are mixed or reacted then component (F) is added, then component (C) is mixed and/or reacted with component (A) and (D) or (B) and/or (A) and (B) in a molar ratio of the amino compound with or without organic compound:aldehyde:phosphorus oxyacid of 1-2:1-2:0.5-1, then component (E) is added and mixed, then the components are mixed and reacted at ambient to 90 degrees C. and at ambient to reduced pressure then component (G) is added to adjust the pH.
