A series of random copolysiloxanes (PCDMS) containing various amount of γ‐cyanopropyl groups are prepared by a new method under mild conditions. Structures of the synthesized polymers are fully characterized by FTIR, 1H NMR, 29Si NMR, and GPC. Rheological properties of PCDMS are tested by cone and plate rheometer, and thermal properties by differential scanning calorimetry (DSC) and thermogravimetry analysis (TGA). Damping properties as well as fuel resistance of the cured PCDMS elastomers are also tested. The correlation between chemical structure, content of cyanopropyl group and properties are discussed. With the increasing amount of polar cyanopropyl group introduced, glass transition temperatures (Tg) of the synthesized PCDMS gradually increases from −121 to −65 °C, residual weight increases from 0 to 36% at 800°C, loss factor reaches as high as 1.74, mass increase under fuel immersion for 14 days can be as low as 3.6%. © 2014 Wiley Periodicals, Inc.

“…7 The solubility in organic solvents decreases with increasing relative atomic mass. While TMSOLi and TMSONa are soluble in diethyl ether, dichloromethane, dimethyl sulfoxide, petroleum ether, benzene, cyclohexane, and carbon tetrachloride, 7,11,12 the potassium salt is less soluble in these solvents and the derivatives of rubidium and cesium do not dissolve at all. 7 K, Rb and Cs salts were analyzed by Grutzmacher et al 13 using X-ray diffraction and described as tetrameric units, where the oxygen and metal ions are arranged in a slightly distorted cube.…”

Trimethylsilanolate alkali salts are widely used in organic synthesis, mainly due to their solubility in common organic solvents. They are frequently used as nucleophiles in ester hydrolysis, both in solution and solid-phase chemistry. However, they have also been used as mild bases or as specific reagents in some chemical transformations. Reactions employing trimethylsilanolate alkali salts as the key component are typically performed under mild reaction conditions. This review summarizes the utilization of trimethylsilanolate alkali salts in various organic transformations.1 Introduction2 Properties of Alkali Metal Trimethylsilanolates (TMSO[M])3 Trimethylsilanolate Alkali Salts in Organic Synthesis4 Conclusion
