    摘要： This invention provides novel azlactone-functional oligomers of 2-alkenyl azlactones in which oligomerization has occurred predominantly via the 2-alkenyl group. Oligomerization of the 2-alkenyl group provides oligomers having 2 to 15 mer units with predominantly carbon-carbon backbone segments. Oligomerized in this fashion, the novel compositions possess azlactone groups which can be reacted with nucleophiles in the normal ring-opening sense. The oligomers are prepared by a novel process in which both Lewis and Bronsted acidic catalysts are effective. The reactive oligomers find utility as crosslinking agents for polymers containing azlactone-reactable nucleophilic groups.

    摘要： Novel fluorinated, acrylamide monomers are prepared from 2-alkenyl azlactones reacted with fluorinated alcohols. The novel monomers have the formula ##STR1## wherein R.sup.1 and R.sup.6 are independently hydrogen or methyl; R.sup.2 and R.sup.3 independently can be an alkyl, cycloalkyl, or aryl group, or R.sup.2 and R.sup.3 taken together with the carbon to which they are joined can form a carbocyclic ring containing 4 to 12 ring atoms;R.sup.4 and R.sup.5 are independently hydrogen or lower alkyl;a is 0 or 1;b is 1 or 2;X is a single bond, CH.sub.2, CH.sub.2 OCH.sub.2, and CH.sub.2 CH.sub.2 OCH.sub.2 ; andR.sub.F is a substantially perfluorinated alkyl, cycloalkyl, or aryl group when b is 1 and perfluorinated alkylene when b is 2.Novel polymers and copolymers can be prepared from the monomers of the invention.

    摘要： A composition of matter comprising an acrylamido-acyl or methacrylamido-acyl oligomer derived from at least one nucleophilic oligomer having at least one amino-, hydroxyl-, or thiol-substituted polyoxyalkylene, polyalkyleneimine, polyester, polyolefin, polyacrylate, or polysiloxane oligomer, said nucleophilic oligomer having a molecular weight in the range of 200 to 20,000 is disclosed. Also disclosed are free radically polymerizable monomer-containing compositions containing said oligomers as well as acrylamido- and methacrylamido-acylated polymers which are thermal or photocured products of said oligomers. In addition, a process is disclosed for providing said acrylamido- and methacrylamido-acylated oligomers which are useful, for example, in coatings, films, printing inks, adhesives, and saturants.
