    摘要： The invention relates to a composition comprising at least 10 wt. % of a binder based on calcium sulfate and 0.005 to 5 wt. % of an additive made of at least one water-soluble salt of a multivalent metal cation, at least one compound which is capable of releasing an anion that forms a poorly soluble salt together with the multivalent metal cation, and at least one polymer dispersant which comprises anionic and/or anionogenic groups and polyether side chains. The invention further relates to a method for producing said composition and to the use thereof as a calcium sulfate flow screed, a flowable calcium sulfate filler compound, or an earth-moist calcium sulfate screed.

    摘要： 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.
