- Аннотация: A synthetic route to frost-resistant siloxane rubbers isdeveloped on the basis of the anionic block copolymerization of amixture of cyclooctamethyltetrasiloxane,hexaethylcyclotrisiloxane, and 1,3,5,7-tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane in the presence of KOH. Theresulting rubbers were used to produce frost-resistant elastomers.According to the results of DSC studies, the glass-transitiontemperature of the frost-resistant rubber is –129 °C; nocrystallization or melting processes of the samples are detectedon the thermograms. The elastomer obtained based on thesiloxane rubber retains its operational characteristics even at thetemperature as low as –123 °C.This work was supported by the Russian ScienceFoundation, project no. 21-73-30030.The NMR, GPC, GLC and TGA studies were performed atthe Collaborative Research Center "Center for PolymerResearch" of ISPM RAS supported by the Ministry of ScienceINEOS OPEN – Journal of Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences 5M.
