A3

Abstract:

A polythioether includes a structure having the formula (I): -R<1>-[-S-(CH2)2-O-[-R<2>-O-]m-(CH2)2-S-R<1>-]n-, wherein R<1> denotes a C2-6 n-alkylene, C3-6 branched alkylene, C6-8 cycloalkylene or C6-10 alkylcycloalkylene group, -[(-CH2-)p-X-]q-(-CH2-)r-, or -[(-CH2-)p-X-]q-(-CH2-)r- in which at least one -CH2- unit is substituted with a methyl group, R<2> denotes a C2-6 n-alkylene, C2-6 branched alkylene, C6-8 cycloalkylene or C6-10 alkylcycloalkylene group, or -[(-CH2-)p-X-]q-(-CH2-)r-, X denotes one selected from the group consisting of O, S and -NR<6>, R<6> denotes H or methyl, m is a rational number from 0 to 10, n is an integer from 1 to 60, p is an integer from 2 to 6, q is an integer from 0 to 5, and r is an integer from 2 to 10. The polythioether is a liquid at room temperature and pressure.
