Alkyl substituted difunctional cyclohexylisocyanates

摘要

This invention pertains to alkyl substituted difunctional cyclohexylisocyanates having an isomer distribution. The isocyanates are represented by the formulas: <IMAGE> I and <IMAGE> II wherein; R1 is C1-4 alkyl; R2 is C1-4 alkyl and n is 0 or 2. The invention also relates to polyurethane and polyurethane/urea resins prepared using the alkyl substituted difunctional cyclohexylisocyanates as at least a portion of the polyisocyanate used in forming the polyurethane.
