Abstract
Bis(N-alkylaminocyclohexyl)methanes are excellent chain extenders in the formation of polyurethane and polyurea polymers, both elastomers and coatings, from both monomeric polyisocyanates and isocyanate-terminated prepolymers. Our chain extenders may be used alone or in combination with other polyamines and with polyols. A broad spectrum of polymeric material can be formed with a range of diverse properties.
