ABSTRACT:
Low molecular weight polydisperse isocyanate-functional acrylic polymers are provided which contain terminal monosulfide groups on at least 10% by number of polymer molecules but are substantially free of toxic monomeric isocyanates.
The polymers are prepared by direct reaction of the monomers, e.g., 2-isocyanatoethyl methacrylate and butyl acrylate, in the presence of a mercaptan chain-transfer agent and a polymerization initiator but in the substantial absence of water and of Lewis-type bases. They can be crosslinked and are useful in a variety of applications such as moisture-curing coating compositions.
