A methacrylic monomer with polyhedral oligomeric silsesquioxanes (FM-28) as a pendant group can be polymerized with 1-24 (X = Br)/CuBr/L-32 in toluene (.MJMn = 1.14).326 Block and star copolymers of this partially inorganic monomer with MA and nBA are expected to function as new hybrid materials.

Perfluoroalkyl groups are also introduced into block copolymers with methacrylates, acrylates, and styrene (B-46 to B-53), which can be synthesized in scCC>2 or in the bulk.95,315 Amphiphilic block copolymers based on glycopolymer segments (B-54 and B-55) are synthesized by copper-catalyzed polymerizations.321,322 Comonomers with a polyhedral oligomeric silsesquioxane unit afforded hybrid polymers between organic and inorganic components (B-56 and B-57).326...

One final class of materials that is being increasingly considered for use in composites is that based on polyhedral oligomeric silsesquioxanes (BOSS) (see Hybrid plastics) (8,14,32-34). A variety of different cage structures have been discovered, but more recently the cubic structure is receiving increased attention... [Pg.7572]

Polyhedral oligomeric silsesquioxanes (POSSs) could be used as building blocks for multifunctional composite solids and for hierarchical inorganic/organic hybrid architectures. These compounds may include inert hydrocarbon moieties, reactive groups, and... [Pg.71]

Recently, ROMP of silicon-containing norbornenes was used for creation of inorganic-organic hybrid materials. Particularly, incorporation of the polyhedral oligomeric silsesquioxanes molecule (POSS) in norbornene and its ROMP copolymerization with norbornene or norbornene-dicarboxylic acid gave POSS-containing copolymers [208, 209],...

Chapter 5 is a review of polyhedral oligomeric silsesquioxanes (POSS), hybrid POSS-organic copolymers, and POSS resin nanocomposites. Although silsesquioxanes have been known since tiie 1960s, only recently, through controlled synthesis and purification, have their structure and unique properties been determined and their useful applications been explored. This chapter is complemented by a discussion of the synthesis and properties of silica- and silsesquioxanes-containing polymer nanohybrids in Chapter 6. Chapter 7 involves a review of the preparation and characterization of siloxane-based polyviologens, polyurethanes, and divinylben-zene elastomers. [Pg.4]

Recently, a series of thermoset organic-inorganic hybrid composites based on several types of octa-functional polyhedral oligomeric silsesquioxane (POSS) was... [Pg.136]
