文摘

Novel thermoplastic poly(thioether sulfone)s, poly(TCDSH/DVS) and poly(BSMD/VSTCD), with high refractive indices and high Abbe鈥檚 numbers have been developed using disulfanyltricyclo[5.2.1.0^2,6]decane (TCDSH) and bis(vinylsulfone)tricyclo[5.2.1.0^2,6]decane (VSTCD) based on tricyclo[5.2.1.0^2,6]decane moiety. TCDSH and VSTCD were easily prepared from dicyclopentadiene via two or three steps and polymerized with divinyl sulfone (DVS) or 2,5-bis(sulfanylmethyl)-1,4-dithiane (BSMD) to give high molecular weight polymers (M_n = 19鈥?00 and 28鈥?00). The flexible, transparent, and amorphous films of poly(TCDSH/DVS) and poly(BSMD/VSTCD) were successfully prepared. They showed a good thermal stability with the 5% weight loss temperatures of around 300 掳C in nitrogen, the glass transition temperatures of 74 and 113 掳C, high refractive indices of 1.6052 and 1.6228, and high Abbe numbers of 48.0 and 45.8, respectively. Poly(TCDSH/DVS) and poly(BMMD/VSTCD) with highly balanced thermal and optical properties are promising candidates for optical application, especially for lens materials.
