| abstract |
The invention provides polyether imidazolidone compounds of the formula:n n wherein R is H or alkyl having 1 to 16 carbon atoms, R¹, R², R³ and R⁴ are selected from hydrogen and alkyl having 1 to 4 carbon atoms, X is -NH₂ or -OH, and a + b equals n, a number having a value of 2 to 80. n The compounds in which X is OH are useful in the preparation of polyurethane foams. The compounds in which X is NH₂ are useful in the preparation of polyurea elastomers, or for the curing of epoxy resins. |
