  Refractive Index Changes in Polymers Bearing Pendant Active Ester Groups by Thermal Rearrangement Reaction

  摘要：

  分别通过自由基和光引发自由基聚合 S-(2-苯并恶唑基)-4-乙烯基硫代苯甲酸酯，选择性地合成了带有 S-(2-苯并恶唑基)硫酯基团的线性和支化聚合物。加热时，悬垂的 S-（2-苯并恶唑基）硫酯基团转化为 3-酰基苯并恶唑啉-2-硫酮基团，两种情况下的折射率（Δn）都发生了约 +0.01 的变化。紫外-可见光谱和红外光谱以及与含有 3-酰基苯并恶唑啉-2-硫酮基团（同样由 3-(4-乙烯基苯甲酰基)苯并恶唑啉-2-硫酮合成）的真实聚合物的比较证实了这种结构转换。应用这种热诱导重排反应可为获得折射率可受热（如激光束产生的热量）改变的材料提供一种新方法。

  The present invention provides an aromatic polyester which is substantially free from the occurrence of coloration and retains significantly high transparency even after being thermally processed at high temperature and which has high flowability. The aromatic polyester contains a polyhydric phenol residue and a residue of any one of aromatic polycarboxylic acid, halide thereof, and anhydride thereof, and terminals of the aromatic polyester have a structure represented by the formula -C(O)-R. The aromatic polyester has an end-capping rate of 90% or higher and a weight average molecular weight (Mw) ranging from 3,000 to 1,000,000.

  Linear and branched polymers bearing S-(2-benzoxazolyl) thioester groups were selectively synthesized by free radical and photoinitiated radical polymerization, respectively, of S-(2-benzoxazolyl)-4-vinylthiobenzoate. Upon heating, the pendant S-(2-benzoxazolyl) thioester groups were converted to 3-acylbenzoxazoline-2-thione groups, accompanied with a change of refractive index (Δn) of about +0.01 in both cases. The structural conversion was confirmed by UV–vis and IR spectroscopy, as well as comparison with authentic polymers bearing 3-acylbenzoxazoline-2-thione groups (similarly synthesized from 3-(4-vinylbenzoyl)benzoxazoline-2-thione). Application of such thermally induced rearrangement reactions may provide a new approach for obtaining materials whose refractive index can be changed by heat (e.g., generated by a laser beam).
