摘要
Sodium salt of styrene/methacrylic acid copolymer was synthesized via radical polymerization, and its absolute molecular mass and polydispersity index were measured by aqueous-based GPC coupled with MALLS in a mixed solvent containing 75/25, v/v%, methanol/water, 38.6 mM NaCl and 10.0 mM NaH2PO4 buffer, pH 6.0. Dynamic light scattering verified the absence of aggregation of copolymer in preferred mobile phase compositions.
