| titleOfInvention | One kind is containing fluorene structured light-cured resin of the double thiophenyls of many ethyoxyls and preparation method thereof |
| abstract | The present invention relates to resin and process for preparing resins technical field, and in particular to one kind is containing fluorene structured light-cured resin of the double thiophenyls of many ethyoxyls and preparation method thereof.The preparation method includes the steps：Take 9.9 (the 4 many ethyoxyls of thiophenyl hydroxyl) double fluorenes and (methyl) acrylic acid to add organic solvent, using organic acid as catalyst, under conditions of polymerization inhibitor and reducing agent are present, carry out esterification；After reaction terminates, progress salt is washed, neutralized, washing, drying, vacuum distillation is removed after solvent, that is, obtains 9.9 described (4 thiophenyls (methyl) acryloyl-oxy Quito ethyoxyl) double fluorenes.The present invention prepares the fluorene structured many ethoxy acrylate resins of containing double benzene sulfenyl for colourless or pale yellow transparent light-cured resin, possesses good heat resistance, the transparency, and different refractive index gradients. |
