Heavily crosslinked Poly(urethanes) (PU) with composed of ether and/or ester macrodiols have been synthesized and subjected to accelerated weathering (i.e., UV-light and water) to assess the effects of the macrodiols on mechanical stability. Data fro

The dielectric properties of composites containing copper-coated tubules in epoxy and polyurethane were characterized and interpreted in terms of contact angle and interfacial tension between the filler and the polymer matrix. The polyurethane sample

Hydrosilation of poly(methylhydrosiloxane) with a fluorinated olefin in supercritical CO2 (scCO 2 ) using Karstedt's Pt catalyst has been successfully demonstrated; results were compared with those obtained in a subcritical conventional solvent, i.e.

A high pressure reactor has been constructed and used for in situ spectroscopic measurements of reaction kinetics in supercritical fluids. The thermal decomposition of 2,2′-azobis(isobutyronitrile) (AIBN) in supercritical carbon dioxide (SC-CO2) wa

Coatings designed for applications as non-toxic non-fouling coatings have been prepared. Conventional coatings used in this application suffer from lack of adhesion to the substrate and lack of mechanical strength. Both of these detriments were overc

Polybutadiyne samples were heated at 20°C/min up to 1200°C in a pyroprobe attached to a gas chromatograph/mass spectrometer (GC/MS). Analysis of the volatiles evolved during heating identified carbon dioxide (adsorbed on polymer surface), methane,

Highly fluorinated aliphatic polyesters were synthesized from a fluorodiol [HOCH2CH2(CF2)8CH2CH2OH] and both sebacoyl chloride and adipoyl chloride. Melt condensation polymerization followed by fractionation resulted in polymer samples with number av

Samples of an acetylene-functionalized polyphenylene resin have been thermally cured to determine the effects on char yield and thermooxidative stability. The material's lack of a processing window led to difficulties in handling; it was found that q

The synthesis of “reactive” ( i.e. aminoacylated) fluoroaliphatic diamines [H2N(CH2)3C(O)NHCH2CH2(CF2)nCH2CH2NHC(O)(CH2)3NH2; n=4,8] has been accomplished through the use of peptide blocking group and coupling techniques. Also, the syntheti
