A polymeric powder composition prepared from an emulsion blend comprising: from 95 to 98.5 percent by weight latex based substrate polymer, wherein the latex based substrate polymer comprises units derived from one or more monomers selected from the group consisting of styrene, methyl methacrylate, vinyl chloride, acrylonitrile, and methacrylic acid, and combinations of two or more thereof and wherein the latex based substrate polymer has an average particle size, measured using a latex diluted to 0.001% solids with a BI 90 (Brookhaven Instruments, Holtsville, NY) particle size detector, utilizing Dynamic Light Scattering (15° and 90° scattering angles) and a laser light source, of between 100 nm and 10 μm; and from 1.5 to 5 percent by weight binder latex polymer, wherein the binder polymer comprises up to 100% by weight units derived from butyl acrylate, ethyl acrylate, and/or ethylhexyl acrylate, and from 0 to 2% by weight (meth)acrylic acid, and wherein the binder polymer has an average particle size, measured using a latex diluted to 0.001% solids with a BI 90 (Brookhaven Instruments, Holtsville, NY) particle size detector, utilizing Dynamic Light Scattering (15° and 90° scattering angles) and a laser light source, of from 50 to 250 nm; wherein a dry powder prepared from the emulsion blend by spray drying exhibits no more than a 25% decrease in median particle size after attrition testing and no more than a 50% increase in the fraction of particles <45μm after the attrition testing, wherein said attrition testing is performed according to the following procedure: First, median particle size and percentage of particle size <45μm of the powder is measured using a light scatter instrument with Malvern Mastersizer (Malvern Instruments, Worcestershire, UK). Then 100 g of 48 mm (3/16") diameter stainless steel ball bearings and 50 g of powder into a solid pan with lid and milled for 10 minutes in a "Ro-Tap" screen shaker instrument (RX30 Ro-tap, W.S. Tyler Inc., Mentor, OH). The powder particle size is then re-measured and the final result recorded is the change before/after in median particle size and %<45μm dust values. from 95 to 98.5 percent by weight latex based substrate polymer, wherein the latex based substrate polymer comprises units derived from one or more monomers selected from the group consisting of styrene, methyl methacrylate, vinyl chloride, acrylonitrile, and methacrylic acid, and combinations of two or more thereof and wherein the latex based substrate polymer has an average particle size, measured using a latex diluted to 0.001% solids with a BI 90 (Brookhaven Instruments, Holtsville, NY) particle size detector, utilizing Dynamic Light Scattering (15° and 90° scattering angles) and a laser light source, of between 100 nm and 10 μm; and from 1.5 to 5 percent by weight binder latex polymer, wherein the binder polymer comprises up to 100% by weight units derived from butyl acrylate, ethyl acrylate, and/or ethylhexyl acrylate, and from 0 to 2% by weight (meth)acrylic acid, and wherein the binder polymer has an average particle size, measured using a latex diluted to 0.001% solids with a BI 90 (Brookhaven Instruments, Holtsville, NY) particle size detector, utilizing Dynamic Light Scattering (15° and 90° scattering angles) and a laser light source, of from 50 to 250 nm; wherein a dry powder prepared from the emulsion blend by spray drying exhibits no more than a 25% decrease in median particle size after attrition testing and no more than a 50% increase in the fraction of particles <45μm after the attrition testing, wherein said attrition testing is performed according to the following procedure: First, median particle size and percentage of particle size <45μm of the powder is measured using a light scatter instrument with Malvern Mastersizer (Malvern Instruments, Worcestershire, UK).
