Abstract:
1. A composition comprising a mixture of nanolatex polymer particles and conventional latex polymer particles in a ratio ranging between about 3:97 and 90:10 (w/w) nanolatex particles to conventional latex particles, the nanolatex particles having an average particle size diameter of 7-30 nm, and the conventional latex particles having an average particle size diameter of 60-800 nm; wherein said nanolatex particles have been separately synthesized via microemulsion polymerization and then blended with the conventional latex particles, wherein the conventional latex, the nanolatex, or both additionally comprise co-monomers that promote crosslinking, wherein the co-monomer is selected from the group consisting 1-3-butylene glycol dimethacrylate (BGDMA), ethylene glycol diacrylate, ethylene glycol dimethacrylate, propylene glycol diacrylate, propylene glycol dimethacrylate, hexanediol diacrylate, hexanediol dimethacrylate, divinyl benzene, glycidyl methacrylate (GMA), acetoacetoxyethyl methacrylate (AAEMA), diacetone acrylamide (DAA), hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxyl ethyl methacrylate, and hydroxypropyl methacrylate and mixtures thereof; wherein the nanolatex particles or the conventional latex particles comprise a polymer which comprises at least the monomers of n-butyl acrylate (nBA) and n-butyl methacrylate (nBMA).
