FIELD: chemistry.
SUBSTANCE: claimed invention relates to thioethers, suitable for application in sealant composition, which contain the structure described by formula (I): -[-S-(RX)p-(R1X)q-R2-]n- (I), in which (a) each of R which can be identical or different stands for C2-10 n-alkylene group; C2-10 branched alkylene group; C6-8 cycloalkylene group; C6-14 alkylcycloalkylene; or C8-10 alkylarylene group ; (b) each of R1, which can be identical or different stands for C1-10 n-alkylene group; C2-10 branched alkylene group; C6-8 cycloalkylene group; C6-14 alkylcycloalkylene; or C8-10 alkylarylene group; (c) each of R2, which can be identical or different stands for C2-10 n-alkylene group; C2-10 branched alkylene group; C6-8 cycloalkylene group; C6-14 alkylcycloalkylene; or C8-10 alkylarylene group ; (d) X stands for O; (e) p has value in the range from 1 to 5; (f) q has value in the range from 0 to 5; (g) n has value in the range from 1 to 60; and (h) R and R1 are different from each other. Also described is method of obtaining such thioethers, sealant compositions which contain them, as well as aerospace flying apparatuses, which contain surface with coating containing thioethers, or a hole, sealed with a sealant composition, which contains thioethers.
EFFECT: obtaining novel thioethers, possessing excellent fuel resistance and resistance to higher temperature with reduced expenditures.
