An article may be formed by contacting a 1,1-dicarbonyl substituted alkene with an activator comprised of an initiating salt and a weak acid and allowing the 1,1-dicarbonyl substituted alkene to cure to form the article. The article may be any useful shape such as a film, coating, layer (e.g., within an additive manufactured article), laminate or the like. The article may be one in which the cured article adheres substrates together.

Provided is a method for producing a polyvinyl alcohol having improved mechanical strength without significantly impairing productivity. A method for producing a polyvinyl alcohol having an average degree of polymerization of 5.0×10.sup.3 or more and 1.5×10.sup.4 or less, the method including steps of: subjecting a vinyl ester-based monomer to suspension polymerization at a polymerization temperature of 10° C. or more and 50° C. or less with a polymerization rate of 10% or more and 70% or less to obtain a vinyl ester-based polymer; dissolving the vinyl ester-based polymer in an alcohol-based solvent; and carrying out a saponification reaction by adding a saponification catalyst to an alcohol-based solution of the dissolved vinyl ester-based polymer.

The present invention relates to a method for forming a polymeric nanocoating on a substrate as well as substrates bearing the polymeric nanocoating. The method comprises exposing the substrate to a plasma comprising one or more unsaturated monomeric species for a period of time sufficient to allow the coating to form on the substrate. The one or more unsaturated monomeric species comprise (i) an aromatic moiety and (ii) a carbonyl moiety. The one or more unsaturated monomeric species also comprise a crosslinking reagent.
