Flame retardant urethane forms containing alkanol amino phosphonates |
| abstract |
Compounds are described which are useful as flame retardants for chemical incorporation into polyurethane and like polymer foams and which have the formula: wherein R1 and R2 are each hydrocarbyl or halohydrocarbyl, CnH2 n is alkylene (Ca-b) and R3 and R4 taken together with the attached C atom are the residue of a cycloalkane, cycloalkene or cycloalkanone. The compounds have two active hydrogen atoms (marked with an asterisk) which show substantially equal reactivity towards isocyanato groups in sharp contrast to closely related compounds hitherto known.
