Polyurethane elastomers and foams prepared from polyamine curing agents |
| abstract |
Amine curing agents for polyurethane foams and elastomers obtained by condensing a monoamine composition with formaldehyde in the presence of a mineral acid. The monoamine can be 2chloroaniline or mixtures of 2-chloroaniline with aniline and/or o-toluidine. The proportions of reactants are selected to produce curing agents which have moderate reactivities and exhibit a limited tendency to crystallize under normal operating conditions. The amine compositions are particularly useful as curing agents in the preparation of polyurethane foams. The new compounds, 3-chloro-4,4''-diaminodiphenylmethane and 3-chloro-3''methyl-4,4''-diaminodiphenylmethane can be obtained from appropriate reaction products. |
