1. A method of producing a solid drag reducing additive, comprising:
forming an emulsified polymer mixture from at least one polar monomer by emulsion polymerization;
disrupting the emulsified polymer mixture by adding a demulsifier and an anti-blocking agent to form the solid drag reducing additive, wherein the demulsifier is selected from the group consisting of C3-C8 ketones and aldehydes;
isolating the solid drag reducing additive;
drying the solid drag reducing additive to 10 wt % or less of water; and
forming a slurry or suspension by adding a carrier fluid to the solid drag reducing additive in a range of about 10 wt. % to about 50 wt. %.
