Recommanded Product: (3aR,4S,7R,7aS)-rel-Hexahydro-4,7-methanoisobenzofuran-1,3-dione《Synthesis and characterization of novel hydrogenated poly(norbornene bisimide)s prepared from ring opening metathesis polymerization》 was published in 2011. The authors were Yoon, Kyung-Hwan;Park, Seung Beom;Park, Insook;Yoon, Do Y., and the article was included in《Bulletin of the Korean Chemical Society》. The author mentioned the following in the article:
We synthesized three novel poly(norbornene bisimide)s by ring opening metathesis polymerization (ROMP) and subsequent hydrogenation. Their thermal, mech. and optical properties were investigated with TGA, DMA, UV-Vis spectrometer, and optical reflectometer. The new polymers showed high glass transition temperatures over 260° and good thermal stability with 5% wt-loss temperature higher than 390°. When solvent casted, they yielded optically transparent and dimensionally stable films with a relatively low coefficient of thermal expansion of about 50 ppm K-1. Therefore, the bisimide moieties substantially enhanced thermal and dimensional stabilities, as compared with normal ROMP-prepared polynorbornene films. Though the water uptake was increased to 0.6%, this water uptake is still considerably lower than that for polyethersulfones (1.4%) or polyimides (2.0 wt-%). Hence, the new poly(norbornene bisimide)s may become attractive candidates for flexible substrates of optoelectronic devices such as displays and photovoltaic solar cells. And (3aR,4S,7R,7aS)-rel-Hexahydro-4,7-methanoisobenzofuran-1,3-dione (cas: 14166-28-0) was used in the research process.
In the laboratory, (3aR,4S,7R,7aS)-rel-Hexahydro-4,7-methanoisobenzofuran-1,3-dione(14166-28-0) is a popular solvent when its water miscibility is not an issue. It is more basic than diethyl ether and forms stronger complexes with Li+, Mg2+, and boranes.Recommanded Product: (3aR,4S,7R,7aS)-rel-Hexahydro-4,7-methanoisobenzofuran-1,3-dione It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents.
