Abstract:
The present invention describes the use of copolymers with a composition gradient as sole stabilizer in emulsion free-radical polymerization. The copolymers of the invention are prepared via controlled free-radical polymerization and comprise at least one hydrophilic monomer such as acrylic acid and at least one hydrophobic monomer such as styrene.
