Mechanical properties of one-pot 2K acrylic latex films prepared from DAAM/ADH

Functional acrylic copolymer latexes were synthesized from methyl methacrylate, butyl acrylate, acrylic acid as commercial monomers and different amounts of diacetone acrylamide (DAAM) as a functional monomer by seeded semi-continuous emulsion polymerization. Adipic acid dihydrazide (ADH) was added to the latex to provide cross-linking at ambient temperature in the films. Mechanical properties of the films were evaluated through hardness measurement and dynamic mechanical thermal (DMTA) analysis. The results proved that the films containing 1 wt% DAAM in copolymer emulsion exhibit improved mechanical properties
