ABSTRACT:
New secondary amines are described which are prepared from inexpensive, commercially available raw materials, are stable at room temperature, and are reactive toward electrophiles. The secondary amines are prepared by the addition of one or more primary amines with one or more male (amide/ester) and fumar (amide/ester) Michael receptors. The above amines can be used as coreactants with aliphatic polyisocyanates for polyurea coatings. The novel secondary amines are also described as particularly useful as part of a two-part liquid pavement marking composition for pavement markings.
