This book was released on 1972 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Work is reported on the synthesis and/or characterization of 30 different compounds for use in studies related to the preparation of high- temperature stable polymers. As a result of this effort, 28 synthesized and/or characterized compounds were submitted as 42 individual samples. The number and type of compounds submitted are identified as follows: Perfluoro-n-alkyl iodides; Divinyl substituted aromatics; Organo-diiodides; Acenaphthene derivatives; Diether linked dicarboxylic acids; Aromatic Disulfonamides; Perfluoroalkylene bisphenols; Perfluorophenyl thiols; Ladder polymer; Substituted polyphenyl ethers; and Substituted phenyl halides. The 42 samples of the submitted compounds ranged in size drom 2.0 to 650.4 g and, in nearly all cases, the purity was at least 99%. Mass spectrometry, infrared spectroscopy, gas liquid chromatography, nuclear magnetic resonance spectroscopy, thin-layer chromatography, differential thermal analysis, viscosimetry, and elemental analysis were employed to establish structure and determine purity.
