Novel polyureas with soft segments based on a difunctional amine, Versalink P-1000, and hard segments based on Isonate 143L, which is a mixture of difunctional and trifunctional isocyanates, were synthesized. The stoichiometric ratio of Isonate 143L to Versalink P-1000 in the polyurea material system was incrementally varied. The properties of the resultant… CONTINUE READING
