Pyrroloimidazole 1a was obtained by using isopropyl bromoacetate as an alkylating agent and phenyl vinyl sulfone
Antimalarial effects of vinyl sulfone
cysteine proteinase inhibitors.
While the sulfones
initially heightened the patients' sense of reaping the benefits of a paternalistic Welfare State that provided for the needs of the most vulnerable, patients' hope for recovery also interacted with changing notions of the rights and obligations of citizenship, deepening a sense of autonomy and instilling a new willingness to challenge and critique.
Removal of sulfones
and sulfoxides, created during oxidation, was carried out by extraction followed by adsorption with silica gel to reach sulfur content levels of 7.
(DCDPS) is used as a starting material in the polymerization of compounds such as Udel, Victrex, and Radel R.
PCB biotransformation has been shown to lead to two classes of PCB metabolites that are present as contaminant residues in the tissues of selected biota: hydroxylated (HO) and methyl sulfone
That wave will include, in Q3, EpiSpire HTS polyethersulfone, the result of a coupling of Solvay and Gharda technologies, which has a glass transition temperature some 45[degrees]C higher than current sulfones
They were primarily polyether ether ketone (PEEK), thermoplastic polyimide (TPI), potybenzimidazole (PBI), high-temperature sulfones
, and polyamide-imide (PAI).
Pearson's correlation coefficients for certain individual and total concentrations of methyl sulfones
of PCBs and DDE versus individual and total concentrations of PCBs and p,p'-DDE in different tissues from 11 subjects.
We take great pride in our legacy of developing and growing sulfone
opportunities across many high-end markets and end-use applications," commented Doug Brademeyer, Sulfones
The purchase provides Solvay with capabilities for developing, manufacturing, and marketing a new range of specialty grades of such polymers as polyetherether ketone (PEEK), high-performance sulfones
, and related monomers.
In '82, GE Plastics launched Ultem PEI, a clear amorphous resin with higher heat performance than sulfones
