摘要
A method for the synthesis of fluorinated allyl-containing bisphenol based on 4,4'-[(2,3,5,6-tetrafluoro-1,4-phenylene)bis(oxy)]diphenol has been elaborated. Curable aromatic polyethers have been prepared via polycondensation of the synthesized bisphenol with decafluorobiphenyl. The influence of bases, namely K2CO3 and NaH, on the molecular weights of polymers has been studied, and the conditions of their curing at allyl moieties have been found. Mechanical, physicochemical, and dielectric properties of allylcontaining polymers are dependent on the method of their preparation and curing.
