  The lactone ring-containing polymer of the present invention meets the following conditions that: (1) the content of polymer gels of 50 µm or greater in average particle diameter is lower than or equal to 100 pieces/100 g, and the weight average molecular weight of the polymer is 50,000 to 170,000; and/or (2) an increasing rate of viscosity after heated at 280°C for 30 minutes is 2.0 times or smaller. The lactone ring-containing polymer of the present invention contains very few foreign matters and does not easily cause gelation, in addition to being excellent in transparency and heat resistance as well as having the desired properties such as mechanical strength and forming and processing properties. The forming material obtained by heating and granulating such a polymer is suitable for use in, for example, optical components such as light guide materials, optical lenses, and optical films.

  本发明的含内酯环聚合物符合以下条件：(1) 平均颗粒直径大于或等于 50 微米的聚合物凝胶含量小于或等于 100 块/100 克，且聚合物的重量平均分子量为 50,000 至 170,000；和/或 (2) 在 280°C 下加热 30 分钟后，粘度增加率为 2.0 倍或更小。本发明的含内酯环聚合物除了具有极佳的透明度和耐热性，以及机械强度、成型和加工性能等所需特性外，还含有极少的异物，不易引起凝胶化。通过加热和造粒这种聚合物得到的成型材料适用于诸如导光材料、光学镜片和光学薄膜等光学元件。
• The osmium-catalyzed aminohydroxylation of Baylis-Hillman olefins

  日期：1999.7

  The Baylis-Hillman class of olefins undergoes a facile osmium-catalyzed aminohydroxylation reaction. The diastereoselectivity for the aminohydroxylation is influenced by the aldehyde-derived substituent, while the acrylate-derived substituent has a minimal effect. A variety of derivatives and close analogs of the Baylis-Hillman product-core failed to aminohydroxylate, emphasizing the unique reactivity of this class of olefins. (C) 1999 Elsevier Science Ltd.
