A study in radiopaque polymeric materials
… too light to be effective. Investigation of copolymers of methylmethacrylate and p-bromostyrene revealed no deleterious effects arising from the aromatically brominated monomer (aliphatic bromination caused UV destabilisation). For effective x-ray absorption a higher level of bromination …

Synthesis and Characterization of Linear and Crosslinked Mono-Sulfonated Poly(arylene ether sulfone)s for Reverse Osmosis Applications
… during the work-up procedures. A series of linear sulfonated poly(arylene ether sulfone)s with varying ms-DCDPS incorporation was synthesized. 1H NMR confirmed the structure of the polymers and size-exclusion chromatography confirmed that the intended molecular weights were achieved. The …
