In coating applications, carboxylated SBR latex acts as a binder that bridges pigment particles and fibrous substrates, yet its rheological profile must be carefully managed to avoid flocculation or settling. The carboxyl functionality enables strong adsorption onto inorganic fillers such as calcium carbonate, clay, and titanium dioxide, because the anionic groups form coordinate bonds...

Emulsion polymerization of carboxylated SBR latex involves a semi-batch process where styrene, butadiene, and carboxylic acid monomers are fed gradually into a reactor containing water, surfactant, initiator, and chain-transfer agents. The carboxyl monomer, often itaconic acid, is partitioned between the aqueous phase and the monomer droplets due to its water solubility, which influences...
