## Abstract PS__βbβ__PMMA copolymers and blends of PS and PMMA were analyzed by the online coupling of LC at the critical point of adsorption and ^1^H NMR. The separation of the polymers was carried out at chromatographic conditions which correspond to the critical point of PMMA and the size exclus

## Abstract Blends and copolymers of PS and PMMA were analysed by LC coupled to ^1^H NMR at the critical point of adsorption. The separation of the polymers was achieved at chromatographic conditions that correspond to the critical point of PS and the sizeβexclusion mode of PMMA. Copolymers and ble
## Abstract A nanocellular PS/PMMA polymer blend foam was prepared, where bubble nucleation was localized in the PMMA domains. The blend, which contains dispersed nanoscale PMMA islands, was prepared by polymerizing MMA monomers in a PS matrix to form highly dispersed PMMA domains in the PS matrix
