Abstract

The invention relates to a composition that contains a binary mixture of bisphenol F and propoxylated bisphenol F. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good handling from a technical point of view and good miscibility with the isocyanate component and render the end product flameproof. For this purpose, the invention devises a composition, which contains a binary mixture of ethoxylated bisphenol F and propoxylated bisphenol F in a weight ratio of 20:80 to 80:20.

Claims (23)

1. A composition comprising

ethoxylated bisphenol F and

propoxylated bisphenol F in a weight ratio of 20:80 to 80:20.

2. The composition of claim 1 , wherein the ethoxylated bisphenol F is obtained by reaction of bisphenol F and ethylene carbonate.

3. The composition of claim 1 , wherein the propoxylated bisphenol F is obtained by reaction of bisphenol F and propylene carbonate.

4. The composition of claim 1 , wherein a molar ratio of bisphenol F:ethoxylating agent is at least 1:2 and/or a molar ratio of bisphenol F:propoxylating agent is at least 1:2.

5. The composition of claim 1 , wherein the weight ratio of ethoxylated bisphenol F to propoxylated bisphenol F is 30:70 to 70:30.

6. The composition of claim 1 , further comprising an alkoxylated resorcinol.

7. The composition of claim 6 , wherein the alkoxylated resorcinol is produced by reaction of resorcinol with a combination of ethoxylating agent and propoxylating agent.

8. The composition of claim 6 , wherein the ethoxylated bisphenol F and propoxylated bisphenol F form a binary mixture and wherein a weight ratio of the binary mixture to the alkoxylated resorcinol is 80:20 to 20:80.

9. A process comprising:

I)

a) adding bisphenol F into a reactor and melting at temperatures between 120° C. and 160° C.

b) adding an alkaline medium and heating to 180° C.

c) adding ethylene carbonate and removal of the carbon dioxide

d) optionally adding an acid for neutralization,

II)

e) adding bisphenol F into a reactor and melting at temperatures between 120° C. and 160° C. f) adding an alkaline medium and heating to 180° C.

g) adding propylene carbonate and removal of the carbon dioxide

h) optionally adding an acid for neutralization, and

III) combining the components produced under (I) and (II), to provide a binary mixture having a I:II weight ratio of 20:80 to 80:20.

10. A polyurethane or a polyisocyanurate made from the composition of claim 1 .

11. A prepolymer, foam, insulation material, coating, lacquer, elastomer, adhesive, sealant and/or composition material comprising polyurethane or the polyisocyanurate of claim 10 .
