The separation of a mixture of three poly(styrene-block-t-butyl methacrylate) copolymers (PS-b-PtBMA), consisting of polystyrene (PS) blocks of similar length andt-butyl methacrylate (PtBMA) blocks of different lengths, was performed using various chromatographic techniques, that is, a gradient liquid chromatography on reversed-phase (C18 and C8) and normal-phase columns, a liquid chromatography under critical conditions for polystyrene as well as a fully automated two-dimensional liquid chromatography that separates block copolymers by chemical composition in the first dimension and by molar mass in the second dimension. The results show that a partial separation of the mixture of PS-b-PtBMA copolymers can be achieved only by gradient liquid chromatography on reversed-phase columns. The coelution of the two block copolymers is ascribed to a much shorter PtBMA block length, compared to the PS block, as well as a small difference in the length of the PtBMA block in two of these copolymers, which was confirmed by SEC-MALS and NMR spectroscopy.

Polymerization Method

The differential microemulsion polymerization method was used to prepare the latex nanoparticles at different amount of monomer. The monomer mixture consists different amount of butyl methacrylate (BMA) that was varied from 5.7 g to 9.7 g. Thin film of latex nanoparticles was prepared using the spin coating method and has been dried at 100°C for 5 minutes. The particle sizes of latex nanoparticles were characterized using Zetasizer nanoseries and the structural properties of the samples was studied using Atomic Force Microscopy (AFM). As the BMA amount increased, the particle sizes of latex nanoparticles has found to decrease from 69.66 nm to 31.16 nm and the roughness has detected to reduce from 3.78 nm to 2.63 nm. We have found that the BMA content in the polymerization has sensitively effect the particle sizes and the structural properties of the latex nanoparticles.
