In this study, we focus on membranes of polyethersulfone and poly(N‐vinyl pyrrolidone) and elucidate the influence of composition on the rheological, diffusion and precipitation properties of solutions which are used for membrane preparation via a non‐solvent‐induced phase separation process. The low‐molar‐mass component of the solution is a mixture of the solvent N‐methyl‐2‐pyrrolidone and the non‐solvent...
In this work, morphological, thermal, viscoelastic and dielectric properties of triblock copolymers consisting of styrene (S) and isoprene (I) blocks are discussed. SIS and ISI triblock copolymers were synthesized by sequential anionic polymerization, three of them exhibiting molecular weights below the entanglement molecular weight Me, three of them exhibiting molecular weights in the order of Me...
In this study, the thermal and rheological properties of polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) diblock copolymers are investigated in order to get information about the optimum foaming temperature. Foams of these diblock copolymers were prepared using the technique of batch foaming with carbon dioxide as environmentally-benign blowing agent. The tailored PS-b-P4VP diblock copolymers...
In this work, the morphological and rheological properties of SAN/PPE blends filled with functionalized multi-walled carbon nanotubes (MWCNT) were investigated. Functionalized MWCNT with polystyrene (PS) were prepared by atom transfer radical polymerization (ATRP). Different molecular weights of grafted PS were achieved by varying the time of polymerization. MWCNT fillers were pre-mixed with SAN by...
