1,3‐Adamantanyl dimethylsiloxane copolymers. Preparation and properties

Thermal and gas permeation properties of copolymers derived from 3‐methacryloxypropyltris(trimethylsiloxy)silane and adamantyl group‐containing methacrylate derivatives

“…Therefore, poly(SiMA) was used to improve gas permeability and support poor membrane formation of adamantane. Furthermore, adamantane and siloxane exhibited good compatibility, because introducing adamantane and siloxane with identical structures as substituents is expected to increase thermal resistance and decrease dielectric constant and photo transparency . In our previous study, we synthesized a novel random copolymer, which comprised polyhedraloligomericilsesquioxane (POSS) with cage‐type structure that is similar to that of adamantane and SiMA .…”

“…Furthermore, adamantane and siloxane exhibited good compatibility, because introducing adamantane and siloxane with identical structures as substituents is expected to increase thermal resistance and decrease dielectric constant and photo transparency. [34][35][36] In our previous study, we synthesized a novel random copolymer, which comprised polyhedraloligomericilsesquioxane (POSS) with cage-type structure that is similar to that of adamantane and SiMA. 37 However, POSS structure is approximately 2.5 times larger than adamantane (structure diameter: POSS, 1.5 nm 38 ; adamantane, 6.5-7.1 Å 39 ).…”

Noncovalent linkage of telechelic oligo(dimethylsiloxanes) via end group attachment of host‐cyclodextrins and guest‐adamantanes or guest‐ferrocenes

“…Poly(dimethylsiloxanes)‐derivatives bearing adamantyl moieties in the main or side chain were mainly synthesized via polycondensation of disilanol‐monomers and studied with focus on their thermal properties and solubility in organic solvents. As a consequence, these compounds are used for high heat‐resist and photo‐resist materials …”

“…As a consequence, these compounds are used for high heat-resist and photo-resist materials. [22][23][24] Another important class of functionalized nanosized materials is represented by cyclodextrin (CD) modified silica gels as chiral stationary phases and selectors, which are able to form inclusion complexes with a variety of hydrophobic molecules like proteinogenic amino acids. [25][26][27][28][29][30][31][32] The molecule inclusion and recognition behaviors as well as the combination of the solubilizing properties of b-CD and the biocompability of poly(dimethylsiloxanes) with grafted CD are also used for drug delivery systems.…”
