    摘要: Polymers which are flexible down to -40.degree.F. and which do not depolymerize appreciably when heated in a closed space at 500.degree. F. or above have the structure ##EQU1## These polymers can be cured to rubbers which are solvent resistant and are flexible over a wide temperature range. Such rubbers are useful for sealing aircraft fuel tanks.
