Crosslinkable coating compositions formulated with dormant carbamate initiator
A crosslinkable coating composition comprising: ingredient A that has at least two protons that can be activated to form a Michael carbanion donor; ingredient B that functions as a Michael acceptor having at least two ethylenically unsaturated functionalities each activated by an electron-withdrawing group; and a dormant carbamate initiator of Formula (1) ##STR00001##
wherein R.sub.1 and R.sub.2 can be independently selected from hydrogen, a linear or branched substituted or unsubstituted alkyl group having 1 to 22 carbon atoms; 1 to 8 carbon atoms; and A.sup.n+ is a cationic species or polymer and n is an integer equal or greater than 1 with the proviso that A.sup.n+ is not an acidic hydrogen; and optionally further comprising ammonium carbamate (H.sub.2NR.sub.1R.sub.2.sup.+OCONR.sub.1R.sub.2). The crosslinkable coating composition can be used for a variety of coating applications including nail coating compositions.
Amino acids react with carbon dioxide (CO2) and form nanofibers and nanoflowers
A method for capturing CO.sub.2 comprising dissolving at least one pure amino acid (AA) in water without the use of a catalyst for establishing protonation of an amino group of the amino acid, adding at least one base solution to the amino acid and water solution to deprotonate the protonated amino group of the amino acid and forming an amino acid-XOHH.sub.2O wherein X is sodium or potassium, and subjecting CO.sub.2 to the amino acid-XOHH.sub.2O to form new nanomaterials is provided. A regenerable nanofiber is disclosed comprising a NaHCO.sub.3 nanofiber, a KHCO.sub.3 nanofiber, or an amino acid nanofiber made from subjecting a CO.sub.2 gas to an amino acid aqueous solvent. Preferably, the amino acid aqueous solvent is one or more of a Gly-NaOHH.sub.2O, an Ala-NaOHH.sub.2O, a Phe-NaOHH.sub.2O, a Gly-KOHH.sub.2O, an Ala-KOHH.sub.2O, and a Phe-KOHH.sub.2O.
