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.
本文描述了一种由廉价、市售原材料制备的新型次级胺,其在室温下稳定,并对亲电体具有反应性。该次级胺是通过将一个或多个主要胺与一个或多个马来酰胺/酯和富马酰胺/酯的迈克尔受体加成而制备的。上述胺可以作为与脂肪族聚
异氰酸酯共反应的共反应剂,用于制备聚
氨酯涂层。这种新型次级胺还被描述为特别适用于作为两部分液态路面标线组成部分的路面标线。
