Abstract
Largely alkylated polyamines which may be viewed as low molecular weight polymers of x-amino-y-methylenephenyl are effective curing agents for a diverse class of urethane prepolymers. The resulting polyurethanes are thermosetting polymers with excellent compression set and tensile strength. Because the properties of the resulting polyurethane vary only slightly near the optimum stoichiometry of curing agent-prepolymer, the use of the curing agents of this invention presents the advantage of being very tolerant of operator mixing error.
