High-solids, aqueous, polymeric dispersions

A very high-solids polymeric dispersion, having a very low percentage of volatile organic compound is prepared by dispersing a plasticized liquid acrylic polymer in water and blending with another high molecular weight polymer dispersion and/or latex in water. This plasticized acrylic polymer dispersion has been found to be useful in combination with high molecular weight polymer dispersion and/or latex containing some smaller diameter particles in the preparation of sealant, caulk, adhesive and coating compositions. Such compositions have a polydisperse particle size distribution due to the larger plasticized liquid acrylic particles and the smaller high molecular weight polymer particles which facilitates higher particle packing densities and hence higher solids content without any undue adverse effect on the dispersion stability and rheological properties. The resulting compositions are more environmentally friendly than solvent based systems, dry quickly, and exhibit good physical properties for sealant use.

Method for forming nanocomposite materials

A method for forming a nanocomposite material includes introducing a nanofiller material having polar end groups into an extruder having a polymeric material therein. An unsaturated shielding material is introduced into the extruder. The unsaturated shielding material reacts with the polar end groups, thereby forming a shielded nanofiller material. The shielded nanofiller material is grafted to the polymeric material, thereby forming the nanocomposite material. The nanofiller material therein is substantially exfoliated, and the nanocomposite material exhibits enhanced physical properties.
