The methyl-d3 dynamics of two relatively similar polymers, poly(α-methylstyrene) (PAMS-d3) and polymethylphenylsilane (PMPS-d3), are investigated via deuterium NMR relaxation experiments. Our analysis of the relaxation data uses the entire solid-ech

We have studied the heterogeneous Wurtz-type polymerization of a number of substituted dichlorosilanes at low temperatures as a function of solvent, metal reductant, reaction temperature, reagent stoichiometry, and additives. At 65°C, aryl dichloros

A series of sensitizing additives for polysilane bilayer photoresists have been identified. These compounds effectively quench the fluorescence of aromatic polysilanes and greatly increase the rate of photooxidation and spectral bleaching in the soli

A means to form a surface with enantiomeric functionality using an achiral molecule is proposed. Specifically, if a meso compound were to be crystallized with the correct orientation, one set of opposing crystal faces would possess opposite handednes

Butamben (butyl p-aminobenzoate) has been formulated to provide long-acting treatment for chronic pain. The suspension, which contains poly(ethylene glycol) and polysorbate 80, was found to yellow under ambient conditions if not adequately protected

The segmental dynamics of solid-state poly(methylphenylsilane) were probed with deuterium solid-echo and two-dimensional exchange (2D-X) NMR via a methyl-d3 label. Between 25 and 50 degreesC, the spectra indicated that the polymer consisted of two fr

The dissolution of a drug delivery system consisting of gentamicin sulfate in a hydrophobic polyanhydride matrix has been examined. The in vitro release of gentamicin is a function of the composition of the dissolution medium, with slower release in

The fluorescence decay kinetics in the copolymer, poly(phenylmethyl-co-p- dimethylanilinemethyl silane) have been studied by steady state and time correlated fluorescence spectroscopy and three absorbing and emitting species are proposed to explain t

A negative-tone surface-imaged resist process based upon the area-selective oxidation of silicon-backbone polymers is described. A bromine-based plasma is the resist developer, where the oxidized polymer inhibits the bromine-initiated etching to yiel
