Abstract
Co-agglomerated dispersions and methods for their preparation are described herein. The co-agglomerated dispersions are prepared by co-agglomerating an anionic polymer dispersion and inert particles. The polymers for use in the co-agglomerated dispersions are derived from one or more monomers including at least one conjugated diene monomer. The inert particles have a particle size of less than 2 μm. Also described herein is an aqueous dispersion including co-agglomerated particles formed from at least one polymer and at least one inert material. Further described herein are foamed polymers, latex-based adhesives, waterproofing membranes, sound absorbing coatings, and methods for their preparation and use.
