Abstract
Low molecular weight isocyanate-functional acrylic polymers prepared by direct reaction of the monomers, e.g., 2-isocyanatoethyl methacrylate and butyl acrylate, in the presence of a mercaptan chain-transfer agent are good coating materials applicable to a substrate as by spraying and curable by contact with moisture.
