A new family of poly(anhydrides) (PA) has been developed which can be cured photochemically to produce degradable networks. These degradable anhydride networks may be useful in orthopaedics as bone cements and as matrices for drug delivery. This syst

Carboxylated polypyrrole-silica colloids are synthesized in aqueous media by the oxidative copolymenzation of molar equivalents of pyrrole and 1-(2-carboxyethyl) pyrrole in the presence of ultrafine (20 nm) silica particles [see Maeda et al., Macromo

Carboxylated polypyrrole colloids are synthesized by post-modification of polypvrrole latex in organic media. The modification begins with solvent exchange of the aqueous colloid into N-methyl pyrrolidone, followed by reaction with bromoacetyl bromid

Polypyrrole colloids are synthesized by an oxidative polymerization of pyrrole by ferric chloride in aqueous media containing a steric stabilizer. Polyvinyl alcohol (125,000 to 186,000 mol. wt., 99% hydrolyzed) was used as the stabilizer to prepare t

Aqueous polypyrrole latex reacted at room temperature with good nucleophiles such as thiols and amines, while alcohols showed no reaction. The reactions were followed by visible, XPS, and ESR spectroscopy, radiolabeling, and conductometric titration.

Fluorescence is one of the molecular spectroscopic properties that is enhanced by placing the molecule on the rough surface of a coinage metal. The surface-enhanced fluorescence (SEF) can be directly observed in steady-state fluorescence experiments.

Selenium colloid was synthesized to quantitative yield from selenous acid using sodium ascorbate as the reducing agent. When pure ascorbate is used, the presence of an added surfactant is required to obtain stable suspensions. Alternatively, exposure
