Abstract

Embodiments of the present disclosure are directed towards β-hydroxyphosphonate functionalized polyols and isocyanate reactive compositions that include the β-hydroxyphosphonate functionalized polyol and a base polyol.

First claim

What is claimed is:

1. A β-hydroxyphosphonate functionalized polyol represented by the following Formula:

where
R is selected from: H or

R 1 and R 2 are each independently selected from: H or CH 3 ,
Ar is: C 6 H 2 ,
n is: 1-5.

2. The β-hydroxyphosphonate functionalized polyol of claim 1 , wherein the β-hydroxyphosphonate functionalized polyol is selected from tris(4-hydroxyphenyl)methane phosphonate, cresol phosphonate, and combinations thereof.

3. An isocyanate reactive composition comprising:
a base polyol; and
the β-hydroxyphosphonate functionalized polyol of claim 1 , wherein the base polyol comprises from 50 to 98 parts of the isocyanate reactive composition based upon 100 parts of a combination of the base polyol and the β-hydroxyphosphonate functionalized polyol, and the β-hydroxyphosphonate functionalized polyol comprises from 2 to 50 parts of the isocyanate reactive composition based upon 100 parts of the combination of the base polyol and the β-hydroxyphosphonate functionalized polyol.

4. The isocyanate reactive composition of claim 3 , wherein the base polyol is a polyester polyol, a polyether polyol, a polycarbonate polyol, or a combination thereof.

5. The isocyanate reactive composition of claim 3 , including an isocyanate, wherein the isocyanate is from 50 to 500 parts of the isocyanate reactive composition based upon 100 parts of the combination of the base polyol and the β-hydroxyphosphonate functionalized polyol.

6. The isocyanate reactive composition of claim 3 , wherein the isocyanate reactive composition has an aromatic group content from 5 to 35 weight percent based upon a total weight of a combination of the β-hydroxyphosphonate functionalized polyol and the base polyol.

7. The isocyanate reactive composition of claim 3 , wherein the isocyanate reactive composition has an phosphorous content from 0.1 to 5.0 weight percent based upon a total weight of the isocyanate reactive composition.

8. A cured product formed from curing the isocyanate reactive composition of claim 3 .

9. The cured product of claim 8 , wherein the cured product is a plaque, a foam, or a film.
