含有联苯结构的高含氟量聚芳醚的制备
Preparation of the Biphenyl-containing Polyarylethers with Highly Fluorinated Contents
摘要
Abstract
A trifluoromethyl-activated dichloro-monomer was synthesized via a two-step procedure including a formation of (4-chloro-3-trifluoromethyl)phenyldiazonium chloride and a coupling reaction.Derived from the dichloro-monomer,five fluorinated polyarylethers were prepared via a nucleophilic aromatic substitution polycondensation in the presence of K2CO3.The fluorinated polymers exhibited excellent thermal stability,and the temperatures at a 5% mass loss(Td,5%) of several polymers were above 500 ℃.A highly fluorinated polyarylether had strong hydrophobicity,judging by its contact angle of 104.7°.Also,these fluorine-containing polymers showed low refractive index and low dielectric constants.These highly-fluorinated polymers may be potential materials using as high-temperature coatings or thin films in optical and microelectronic fields.关键词
