Several samples of polystyrene and copolymer of styrene and butyl acrylate containing methacrylamide and/or acrylic acid synthesized by non-seeded semi-batch emulsion polymerization were characterized using gel permeation chromatography coupled with a multi angle laser light scattering photometer (GPC-MALLS). Molecular weight distribution varied with the polymer composition. The obtained GPC-MALLS data showed extraordinary GPC behaviour of the prepared samples. The data hint the presence of branched molecules and microgels in the measured samples.
