Abstract
Semicrystalline, waterborne copolymer latexes of stearyl acrylate-co-short chain (meth)acrylate (a mixture of methyl metacrylate, n-butyl acrylate, acrylic acid and acrylamide) have been synthesized by using different 2-step polymerization strategies. The effect of monomer composition and polymerization strategies on the crystallinity and mechanical properties of polymer films were investigated. These semi-crystalline latexes were successfully used as binders in paint formulations and the effect of crystallinity and copolymer microstructure on the mechanical properties (e.g. hardness, scrub resistance, etc.) and hydrophobicity of the paint films was studied.
