摘　　要： 通过2,2′一二巯基二乙硫醚(MES)与环氧氯丙烷反应,合成了一种新型高折射率、低色散的2,2′一二巯基二乙硫醚缩水甘油醚型光学环氧树脂(DGEMES)。采用红外光谱和核磁共振谱图表征了该树脂的结构,并详细讨论了直接法和间接法合成DGEMES的各种反应条件对产率的影响。得出直接法制取DGEMES的最佳原料配比为:n(MFS):n(环氧氯丙烷):n(Na0H)=1:5:1.9,产率为91.81％,折射率为1.5450;间接法制取DGEMES中的最佳原料配比为:n(MES):n(环氧氯丙烷):n(Na0H)=1:2.4:6,产率为99.32％,折射率为1.5661。 Bisβ - epoxypropylthioetheyl) sulfide (DGEMES) was synthesized from 2,2'-dimercaptoethyl sulfide (MES) and epichlorohydrin(ECH) and its structure was characterized by FT-IR and 1H -NMR. Many factors affected the yield of DCEMES prepared by indirect and direct process were discussed in detail. The optimum reaction condition was obtained : (1) by direct method , the molar ratio of MES, ECH and NaOH was equal to 1: 5:1.9,and the yield and refractive index of DGEMES were respectively 91. 81% and 1. 5450; (2) by indirect method, the molar ratio of MES, ECH and NaOH was equal to 1:2. 4 = 6, and the yield and refractive index of DGEMES were respectively 99.32% and 1.5661.
