ABSTRACT:
Disclosed are novel isocyanate prepolymers and novel secondary amines, both prepared from alkyl diisocyanates and secondary isopropyl derivatives of polyoxyalkylene diamines. The molar ratios, reaction procedures (i.e. inverse addition of reactants) and solvent determine the products. Most of the products are light colored and nongelled.
The isocyanate prepolymers are useful in the field of polyurethanes and the novel secondary amines are useful in epoxy coatings applications.
