摘要： Oligomers of hexafluoropropene are prepared by oligomerization of hexafluoropropene in an organic solvent in the presence of a halide compound and a crown ether. The selectivity to the dimer or trimer may vary depending on the kind of solvent. For example, the oligomerization of hexafluoropropene in acetonitrile or methylene chloride in the vicinity of room temperature gives the dimer thereof at high selectivity. Use of N,N-dimethylformamide favors the formation of the trimer at high selectivity.
摘要翻译： 六氟丙烯的低聚物通过在卤化物和冠醚的存在下在有机溶剂中低聚六氟丙烯来制备。 对二聚体或三聚体的选择性可以根据溶剂的种类而变化。 例如，在室温附近的六氟丙烯在乙腈或二氯甲烷中的低聚使其二聚体以高选择性。 使用N，N-二甲基甲酰胺有利于以高选择性形成三聚体。

摘要： The present disclosure relates to a passivation layer comprising a photocrosslinked fluoropolymer and a process for forming the layer. Passivation layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity and are able to be photoimaged so as to provide the very fine features needed for modern electronic equipment.
