一种高折射率含硫光学共聚树脂的制备方法
摘要：
本发明公开了一种高折射率含硫光学共聚树脂的制备方法，包括：将2‑萘酚与二氯化硫搅拌反应，得到1，1’‑硫代双(2‑萘酚)；将1，1’‑硫代双(2‑萘酚)中加入过量三乙胺进行碱化反应，再滴加丙烯酰氯搅拌反应，得到2,2’‑双(2‑丙烯酰氧基)‑1,1’‑硫代联二萘；将2,2’‑双(2‑丙烯酰氧基)‑1,1’‑硫代联二萘和甲基丙烯酸甲酯、苯乙烯在偶氮二异丁腈作为引发剂条件下进行共聚，加热固化，得到所述高折射率含硫光学共聚树脂。本发明通过在该光学共聚树脂的合成单体中引入包含摩尔折射度大的含硫富电子共轭结构单元的单体来提高共聚树脂的折射率，并与甲基丙烯酸甲酯、苯乙烯共聚制成透明树脂。
摘要（英）：

The invention discloses a preparation method of high refractive index sulfur-containing optical copolymerized resin. The preparation method comprises the following steps: stirring 2-naphthol and sulfur dichloride to react to obtain 1,1'-sulfobis(2-naphthol); adding the 1,1'-sulfobis(2-naphthol) into excessive triethylamine for quaternization, then dropwise adding acryloyl chloride, and stirring and reacting to obtain 2,2'-bis(2-acroloyloxyl)-1,1'-sulfobinaphthyl; and copolymerizing the 2,2'-bis(2-acroloyloxyl)-1,1'-sulfobinaphthyl, methyl methacrylate and styrene in a condition that azodiisobutyronitrile serves as an initiator, and heating and curing the mixture to obtain the high refractive index sulfur-containing optical copolymerized resin. By introducing a sulfur-containing monomer rich in electronic conjugated structural units with great molar refrangibility into a synthesized monomer of the optical copolymerized resin, the refractive index of the copolymerized resin is improved and the monomer is copolymerized with methyl methacrylate and styrene to prepare transparent resin.
