Abstract: Articles comprising a substrate coated with selected isocyanatoalkyl (meth)acrylate polymers or copolymers, e.g., a copolymer of 2-isocyanatoalkyl methacrylate and butyl acrylate, are claimed.

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.

Abstract: Low molecular weight polydisperse isocyanate-functional acrylic 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.

Abstract: Organic carboxylic acid containing from 2 to 12 carbon atoms and having at least two carboxyl groups or at least one carboxyl group and one amino or hydroxy group or anhydride or halide of such acid is used in making aqueous, foam-growth-controlling printing ink composition for use in chemical embossing of heat-foamable and expandable resinous materials such as polyvinyl chloride.

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.

Abstract: Low molecular weight isocyanate-functional acrylic polymers are provided, which contain at least 10% by weight of copolymerized isocyanatoalkyl (meth)acrylate, are substantially free of toxic monomeric isocyanates, and have the following general structure: ##STR1## where R is alkyl or aryl,R.sub.1 is hydrogen or methyl;X is COO--A--NCO or a mixture of COO--A--NCO and at least one of phenyl, COOR.sub.2, ##STR2## Cl, H; where A is an alkylene group having 2-6 carbon atoms, andR.sub.2 is an alkyl group having 1-18 carbon atoms;and n is 2-400.These polymers can be crosslinked and are useful in a variety of applications such as finishes, pigment surface treatments and dispersants, and rheology control agents.
