Vibrational spectra of crystalline octakis(organylsiloxanes): Vibrational spectra of crystalline octakis(organylsiloxanes). Kostrovskii, V. G.; Kanev, A. N.; Gorsh, L. E. (USSR). Zh. Prikl. Spektrosk., 40(3), 399-404 (Russian) 1984. 17865-85-9 and 18971-70-5 which are cas registry numbers are also used here. CODEN: ZPSBAX. ISSN: 0514-7506. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) Vibrational spectra of cryst. methyl-, ethyl- and vinyloctasilioxanes were obtained at 100-1000 cm-1. The anal. of positions and intensity of vibration bands of Si-O-Si and Si-C bonds nos. carried out. The anal. should that the intramol. motion of these groups of atoms is highly correlated and define the high characterization of the vibrational spectra of the given set of octa(organylsiloxanes). .

DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Compns. include blends of ethylene-based polymers and polyhedral oligomeric silsesquioxanes (POSS) or polyhedral oligomeric silicates (POS), having hydrocarbon substitution. The addn. of POSS enhances the mech. properties of ethylene-propylene copolymers by behaving as a phys. crosslinker. .
