Abstract
There is provided herein a polyurethane foam-forming composition comprising a hydroxyl-functional phosphonate of the general formula (I): wherein R1-R4 are as described herein. There is also provided a polyurethane comprising the reaction product of the polyurethane foam-forming composition and a process of making a laminated polyurethane comprising laminating a textile to a polyurethane, preferably a polyurethane foam.
Claims21
A polyurethane foam-forming composition comprising:
- (i) a polyol;
- (ii) an isocyanate;
- (iii) a catalyst;
- and,
- (iv) a hydroxyl-functional phosphonate of the general formula (I):
- where each of R1 and R2 are each independently a linear or branched alkyl group of up to about 6 carbon atoms, or where R1 and R2 are joined to each other in order to form a substituted or unsubstituted ring of from 2 to about 12 carbon atoms, and R3 and R4 are each independently hydrogen or a linear or branched alkyl group of up to about 3 carbon atoms.
A process of making a laminated polyurethane comprising laminating a textile to a polyurethane foam, wherein the polyurethane foam comprises the reaction product of
- (i) a polyol;
- (ii) an isocyanate;
- (iii) a catalyst;
- and,
- (iv) a hydroxyl-functional phosphonate of the general formula (I):
- where each of R1 and R2 are each independently a linear or branched alkyl group of up to about 6 carbon atoms, or where R1 and R2 are joined to each other in order to form a substituted or unsubstituted ring of from 2 to about 12 carbon atoms, and R3 and R4 are each independently hydrogen or a linear or branched alkyl group of up to about 3 carbon atoms.
A laminated polyurethane comprising a reacted hydroxyl-functional phosphonate of the general formula (I):
- where each of R1 and R2 are each independently a linear or branched alkyl group of up to about 6 carbon atoms, or where R1 and R2 are joined to each other in order to form a substituted or unsubstituted ring of from 2 to about 12 carbon atoms, and R3 and R4 are each independently a hydrogen or a linear or branched alkyl group of up to about 3 carbon atoms.
