Embodiment 1

[0148] Phosphorus-Rich Polymer (PRP) Form 1

[0149] Decomposition of phosphorus pentoxide to orthophosphate using alcohol yields an equimolar mixture of diesters and monoesters.

[0150] P 2 o 5 +3ROH=>H 2 RPO 4 +HR 2 PO 4

[0151] This method is used to prepare water treatment chemicals. If the alcohol is 1,4-butanediol and the reaction is carried out in the first stage phosphorus pentoxide distributor / reactor, the structure of the resulting product can be represented as follows:

[0152]

[0153] The preparation method is very simple and yields a light brown resin of medium viscosity.

[0154]Low-cost intumescent coatings are produced by crosslinking similar resins and variants with amino resins.

[0155] 3 moles of 1,4-butanediol were charged into the above first reactor. Charge 2 moles of phosphorus pentoxide in the powder hopper. The contents of the reactor were heated to 45°C. Start stirring.

[0156] Begin to add phosphorus pentoxide continuously. The ...

Embodiment 2

[0171] PRP Form 2

[0172] Form 2 products are curing agents and crosslinkers for phenolic resole resins, and the structure and chain length can vary significantly, making these phenolic resin curing agents useful for different applications. Forms 3 and 4 hereafter preferably use ethanol as the terminating and initiating alcohol, whereas the oligomers of form 2 use isopropanol or n-butanol as the terminating and initiating alcohol. These alcohols reduce the viscosity of the oligomers and thus the resin mixture. Since phenolic resole resins are usually applied to fiber-reinforced composites, the lower viscosity facilitates penetration and wetting of the fibers. Additionally, it is useful to leave a small amount of un-decondensed pyrophosphate linkages in the chain structure. The pyrophosphate is condensed under the action of the water released by the condensation of the resin, thus fully curing the resole phenolic resin at room temperature by providing a certain acidity. The...

Embodiment 3

[0189] Forms 3 and 4

[0190] Form 3 materials are very low acid number partial phosphate esters used to make intumescent films, glues and coatings. Partial phosphates of Form 3 are crosslinked using addition reactions of organic acidic orthophosphate groups. The organic acidic orthophosphates act like carboxylic acids, so any system for crosslinking carboxylic acid functional resins can be used to crosslink low acidity polymeric orthophosphates. Thus, depending on the crosslinker and acid value, cycloaliphatic epoxides, polyfunctional aziridines, polycarbodiimides, zinc ammonium complexes and zirconium ammonium complexes can be used at room temperature or at elevated Cross-linking at temperature.

[0191] Form 4 material is pH neutral and hydroxyl functional. Reaction with isocyanates thus gives polyurethanes and thus non-flammable polyurethane products which are not flammable under the usual test requirements. Depending on the type and amount of isocyanate and polyol sel...

Abstract

A method for producing a polymeric material comprises reacting a first reactant with a second reactant. The first reactant comprises anhydrous phosphorous pentoxide and the second reactant comprises an alcohol. A method for producing a polymeric salt material comprises reacting a first reactant comprising an amine with a second reactant comprising a phosphate ester.

Description

field of invention [0001] The present invention relates to methods of preparing polymeric materials and various materials prepared using the methods. More particularly, but not limited to, the present invention relates to methods of making phosphorus-rich polymers and methods of making phosphate esters (eg, partial phosphate esters). Background of the invention [0002] Expansion is the process by which solid matter transforms into a stiffer expanding foam when heated. Due to the expansion, the thermal conductivity of this foam is significantly lower than that of the original substance, which allows it to be used for fire protection. The intumescent product is applied in its unexpanded form to the surfaces of materials and structures to be protected against fire. [0003] The expanded carbon consists of amorphous carbon or carbon and graphite and condensed phosphoric acid. The char itself is non-flammable. The rationale is that a polymer material is non-flammable if it i...
