摘　　要：以含双巯基型的4,4’-二巯基二苯硫醚与甲基丙烯氯反应,一步法合成了高折射率甲基烯丙基型双巯酯基单体。合成的4,4’-二(甲基烯丙基巯酯基)二苯硫醚折射率为1.654。研究了缚酸剂种类、甲基丙烯酰氯与4,4’-二巯基二苯硫醚摩尔比对产物收率的影响。通过紫外光固化方法制备了聚(4,4’-二(甲基烯丙基巯酯基)二苯硫醚)涂层,涂层在2μm处的折射率为1.626,硬度为3H,附着力为2级,透光率较高。New high refractive index poly（thioester）s （PTEs） containing doublethioesterhavebeen synthesised. PTEs were synthesized by the poly-condensation reaction of methyl acryloyl chloride with 4,4＇-Thiodibenzenethiol. The refractive index of 4, 4＇-bi[methylallylthioester]-diphenyl sulfide wasl.654. The yield was affected by the acid binding agent and mole ratio of raw materials. The homo-polymerization coating was prepared by photo polymerization under UV irradiation. The refractive index of coatings ofpoly-4,4＇-bi（methylaUylthioester）-diphenylsulfidewas 1.626 at 2μm. The hardness and adhesive forceofthe coating achieved 3H and grade 2.
