Rheological Behavior of Entangled Polystyrene - Polyhedral Oligosilsesquioxane ( POSS ) Copolymer (
We report on the linear viscoelastic properties of a family of entangled linear thermoplastic nonpolar hybrid inorganic-organic polymers: random copolymers of polystyrene (PS) and styryl-based polyhedral oligosilsesquioxane (POSS), R7(Si8O12)(C6H4CHdCH2), with R ) isobutyl (iBu). A series of styrene-styryl POSS random copolymers with 0, 6, 15, 30, and 50 wt % iBuPOSS were investigated. WAXS and...

متن کاملPolyhedral Oligomeric Silsesquioxane (POSS)-Based Polymers
A diverse and entirely new class of monomer and polymer technology based on polyhedral oligomeric silsesquioxane (POSS) reagents has been developed. POSS reagents are unique in that they are physically large (approx. 15 Å diameter and 1000 amu) and are composed of a robust silicon–oxygen framework that can be easily functionalized with a variety of organic substituents. Appropriate functionaliz...
