A series of fluoropolymer films was synthe- sized by reacting 1,3-bis(1,1,1,3,3,3-hexafluoro-2-penta- fluorophenylmethoxy-2-propyl)benzene (12F-FBE) with a series of bisphenol monomers via a polycondensation reaction. The biphenols used included a di

A series of fluoropolymer films were synthesized by reacting several bisphenol monomers with 1,3-bis(1,1,1,3,3,3-hexafluoro-2-pentafluorophenyl methoxy-2-propyl)benzene via a nucleophilic aromatic substitution to form polyethers. The bisphenols used

The purpose of this project was to synthesize fluorinated polyimide (PI) nanocomposite membranes in order to study the gas permeation rates and selectivity of carbon dioxide and methane. PIs were synthesized from 2,2-bis(3,4-anhydrodicarboxyphenyl)he

New silicone-containing polymers with crosslinkable units have been synthesized by hydrosilation polymerization in both toluene and supercritical carbon dioxide (70°C, 3000 psi) catalyzed by platinum-divinyltetramethyldisiloxane (Pt-DVTMS). It was f

Poly (methyl methacrylate) (PMMA) is a very good option for electron-beam resists, but suffers from poor radiation sensitivity and poor plasma etch resistance. These problems can be offset, at least in part, by functionalizing the PMMA with photo-lab

A series of aromatic polyesters containing 1,6-diazaspiro[4,4]-nonane-2,7-dione were synthesized under phase-transfer conditions. The copolymers were obtained in essentially quantitative yield, theses were soluble in common organic solvents, and woul
