• Process for producing monoester from dicarboxylic acid fluoride
  申请人：Nippon Mektron, Limited

  公开号：US06407282B1

  公开（公告）日：2002-06-18

  Monoester monoacid fluoride of dicarboxylic acid is produced by allowing dicaroxylic acid fluoride represented by the following general formula: FOCCF(CF3)OCF2(A)p(CF2)qCOF where A is a bifunctional perfluorinated group having 1 to 10 carbon atoms; p is 0 or 1; and q is 0 or an integer of 1-10, to react with an alcohol having at least 3 carbon atoms, thereby esterifying the terminal CF2COF group. Such selective monoesterification reaction is effective for separation and purification of a dicarboxylic acid difluoride isomer mixture comprising symmetrical dicarboxylic acid difluoride and asymmetrical dicarboxylic acid difluoride.

  二羧酸氟单酯单酸是通过让以下一般公式表示的二羧酸氟化物：FOCCF(CF3)OCF2(A)p(CF2)qCOF（其中A是具有1至10个碳原子的双官能团；p为0或1；q为0或1至10的整数）与至少有3个碳原子的醇反应而产生的，从而酯化末端CF2COF基团。这种选择性的单酯化反应对于分离和纯化包括对称二羧酸二氟化物和非对称二羧酸二氟化物的二羧酸二氟化物异构体混合物是有效的。

  Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high T g , thus being stable, and a parabolic refractive index profile due to the presence of the dopant.
