Abstract: Provided herein are dispersible copolymer powders and asphalt compositions comprising the same. The dispersible copolymer powders comprise a core polymer having a glass transition temperature (Tg) of 40° C. or less and a shell comprising a water soluble protective colloid polymer having a Tg of 50° C. or greater. The core polymer can be derived from a vinyl aromatic monomer, a 1,3-diene monomer, and optionally one or more ethylenically-unsaturated monomers. The protective colloid polymer can be selected from a polyvinyl alcohol, a polyvinyl pyrrolidone, a polysaccharide, other water soluble polymers, or a combination thereof. Methods of preparing a styrene-butadiene modified asphalt without significantly increasing the viscosity, comprising adding the dispersible copolymer powder to an asphalt composition, wherein the addition of the copolymer polymer increases the viscosity of the asphalt by 100% or less at 135° C. within 2 hours of mixing are also described herein.

Abstract: The invention relates to a process for modifying polymer particles of an aqueous polymer dispersion in which positively or negatively charged polymer particles are provided with an inorganic salt shell. The inorganic shell leads to an improved drying ability and storage stability of the latex and improves the storage stability of the resulting polymer powder. The obtained polymer powder exhibits an improved viscosity and faster skin-forming time in the final application and is therefore particularly useful in a building material composition.

Abstract: The invention relates to a process for preparing core-shell particles having a polymer core and a continuous silica shell. The in situ formed core-shell architecture suppresses film formation of the polymer and simplifies the subsequent drying process. The finally obtained free flowing polymer powder exhibits improved redispersibility and storage stability and imparts building material compositions improved viscosity and faster skin-forming time.

Abstract: The invention relates to a process for preparing foamed polymer-modified bitumen compositions and to the use thereof for the production of asphalt. The invention also relates to foamed polymer-modified bitumen compositions obtainable by this process. Furthermore, the invention relates to a process for producing an asphalt composition and to the use thereof in road applications. The process for the preparation of the foamed polymer-modified bitumen composition comprises the following steps: i) Heating and pressurizing a bitumen to obtain a hot flowing bitumen stream, ii) Injecting under pressure an aqueous polymer dispersion into the hot flowing bitumen stream obtained in step i), to obtain a pressurized flowing mixed stream of the bitumen and the aqueous polymer dispersion; iii) Expanding the flowing mixed stream, in particular to atmospheric pressure, such that the water contained in the aqueous polymer dispersion vaporizes and foams the mixed stream to obtain a foamed polymer-modified bitumen.
