| description | Un politioéter que contiene sulfona que comprende un resto de Fórmula (1): -A-CH2-CH2-S(O)2-CH2-CH2-A- (1) en donde cada A es independientemente un resto de Fórmula (2): -S-R1-S-(CH2)p-O-(R2-O)m-(CH2)2-S-R1-]n-S- (2) en donde: cada R1 comprende independientemente alcanodiilo C2-10, cicloalcanodiilo C6-8, alcanocicloalcanodiilo C6-10, heterocicloalcanodiilo C5-8, o -[(-CHR3-)s-X-]q-(-CHR3-)r-, en donde: s es un número entero de 2 a 6; q es un número entero de 1 a 5; r es un número entero de 2 a 10; cada R3 comprende independientemente hidrógeno o metilo; y cada X comprende independientemente -O-, -S- y -NR5-, en donde R5 comprende hidrógeno o metilo; y cada R2 comprende independientemente alcanodiilo C1-10, cicloalcanodiilo C6-8, alcanocicloalcanodiilo C6-14 o -[(- CHR3-)s-X-]q-(-CHR3-)r-, en donde s, q, r, R3, y X son como se definen para R1; m es un entero de 0 a 50; n es un número entero de 1 a 60; y p es un número entero de 2 a 6; en donde el politioéter que contiene sulfona es líquido a temperatura ambiente.
Sulfone-containing polythioethers, compositions containing sulfone-containing polythioethers, methods of synthesizing sulfone-containing polythioethers and the use of sulfone-containing polythioethers in aerospace sealant applications are disclosed. The sulfone-containing polythioethers have sulfone groups incorporated into the backbone of the polythioether. Cured sealant compositions comprising the sulfone-containing polythioethers exhibit enhanced thermal resistance. |
