Title: Process for the formation of polyhedral oligomeric silsesquioxanes
IPC: C08G77/38
Filed: 2000-08-03
Abstract: Three processes for the manufacture of polyhedral oligomeric silsesquioxanes (POSS) which utilize the action of bases that are capable of either attacking silicon or any compound that can react with a protic solvent (e.g. ROH, H2O etc.) and generate hydroxide [OH]<->; alkoxide [RO]<->, etc. The first process utilizes such bases to effectively redistribute the silicon-oxygen frameworks in polymeric silsesquioxanes [RSiO1.5] INFINITY  where  INFINITY =1-1,000,000 or higher into POSS nanostructures of formulas [(RSiO1.5)n] SIGMA #, homoleptic, [(RXSiO1.5)n] SIGMA #, functionalized homoleptic, [(RSiO1.5)m(R'SiO1.5)n] SIGMA #, heteroleptic, and {(RSiO1.5)m(RXSiO1.0)n} SIGMA #, functionalized heteroleptic nanostructures. The second process utilizes base to aid in the formation of POSS nanostructures of formulas [(RSiO1.5)n] SIGMA #, homoleptic and [(RSiO1.5)m(R'SiO1.5)n] SIGMA #, heteroleptic and [(RSiO1.5)m(RXSiO1.0)n] SIGMA #, functionalized heteroleptic nanostructures from silanes RSiX3 and linear or cyclic silsesquioxanes of the formula RX2Si-(OSiRX)m-OSiRX2 where m=0-10, X=OH, Cl, Br, I, alkoxide OR, acetate OOCR, peroxide OOR, amine NR2, isocyanate NCO, and R. The third process utilizes base to selectively ring-open the silicon-oxygen-silicon (Si-O-Si) bonds in POSS structures to form POSS species with incompletely condensed nanostructures. These proceses also afford stereochemical control over X. The three processes result in new POSS species that can undergo additional chemical manipulations to ultimately be converted into POSS-species suitable for polymerization, grafting, or other desirable chemical reactions.

Abstract: A network address translation gateway provides normal network translation for IP datagrams traveling from a local area network using local IP addresses to an external network, but suspends source service address (port) translation when the port is reserved for a specific protocol, such as the ISAKMP "handshaking" protocol that is part of the IPSec protocol model. ISAKMP exchanges require both source and target computers to use the same service address (port). By providing a network interface that does not translate the source service address (port), this gateway enables the initiation and maintenance of secure, encrypted transmissions using IPSec protocol between a local area network using local IP addresses and servers on the internet.
