Abstract: Disclosed are compositions comprising polyesters containing a chain of residue of: diols and diesters along the chain, wherein at least a portion of the diesters are 1, 1-diester-1-alkenes, and the chains have alkene groups incorporated into the chains; the composition comprising one or more of the following: i ether groups derived from alcohols, diols, polyols, or a combination thereof obtained via Michael addition to the alkene groups and a residue of the alkene groups remaining after Michael addition; ii the formed polyesters contain one percent or less of residual 1, 1-diester-1-alkene which are unreacted; iii one or more free radical inhibitors; and iv a stabilizer comprising one or more of: oxo acids phosphorous or esters thereof, aluminum sulfate, stannous pyrophosphate, stannous sulfate, aluminum dihydrogenphosphate or decomposition products thereof. The stabilizer is present in an amount sufficient to enhance stability of the polyester without lowering reactivity of the polyester.

Abstract: 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.

Abstract: A method forming a blocked 1,1-dicarbonyl substituted comprises reacting an alkene of a 1,1-dicarbonyl substituted alkene with a blocking Michael addition donor compound such as an alcohol or thiol. The blocked 1,1-dicarbonyl substituted alkene may be polymerized by providing sufficient thermal energy whereby at least portion of the blocked alkenes revert to alkenes and may be addition polymerized or Michael added with a multifunctional Michael addition donor compound (e.g., polyol or polythiol).

Abstract: A method including forming a formulation by contacting one or more photoinitiators with a composition including one or more 1, 1-disubstituted alkene compounds having a purity of about 85 mole percent or more based on total weight of the 1, 1-disubsituted alkene compounds; and exposing the formulation to ultraviolet radiation for initiating free radical polymerization, anionic polymerization, or both, to cure the formulation to form a non-tacky surface. The teachings also contemplate a polymer prepared according to the methods as disclosed.

Abstract: Compositions comprising a) one or more polyester macromers containing one or more chains of the residue of one or more diols and one or more diesters wherein the residue of the one or more diols and the one or more diesters alternate along the chain and a portion of the diesters are 1,1-diester-1-alkenes and at least one terminal end comprises the residue of one of the 1,1-diester-1 alkenes and wherein one or more terminal ends may comprise the residue of one or more diols; and b) one or more polymers having pendant Michael Addition donor groups. Disclosed are coating prepared from these compositions.
