The CP/MAS 13C-NMR spectrum of bis(3,4-dicarboxyphenyl)-dimethylsilane dianhydride (SiDA) as well as the spectra of the N-methyl and N-n-propyl bisimides derived from this dianhydride confirm the occurrence of solid state charge transfer complex (CTC

Comparison of solution and solid-state proton decoupled 13 C NMR spectra have provided evidence for charge transfer complex formation in some diimides and dianhydrides and have indicated the steric limitations which prevent this phenomenon from occur

The interatomic distances for crystalline pyromellitic dianhydride (PMDA) were calculated from x-ray crystallographic data. The CP-MAS 13C NMR spectrum of PMDA was found to be consistent with and accountable for in terms of these distances after lite

A series of polyimide films prepared from 4,4'-oxydiphthalic anhydride (ODPA) and selected diamines were compared with those from pyromellitic anhydride (PMDA), 3,4,3',4'-biphenyltetracarboxylic dianhydride (BPDA) and benzophenonetet racarboxylic dia

The mechanism of the low profile behavior in certain single-phase polyester systems has been examined. It appears that as polymerization occurs, crosslinked beads (< 1μ) of polymer separate from the bulk solution. As the temperature rises, liquid mo
