The invention provides a method for synthesizing 1,4-di(difluoro phenoxy methyl) benzene. The method comprises the following steps: (1) by taking 1,4-di(difluoro methyl) benzene as an initial raw material, and carrying out a free radical substation reaction with chlorine in the presence of a free radical initiator so as to obtain 1,4-di(chlorine difluoro methyl) benzene; (2) without refining of the intermittent, namely the 1,4-di(chlorine difluoro methyl) benzene, directly carrying out a unimolecule free radical nucleophilic substitution reaction on the intermittent with an alkali and phenol in an organic solvent, and carrying out recrystallization on a crude product, thereby obtaining the 1,4-di(difluoro phenoxy methyl) benzene. The method is gentle in reaction condition, and the obtainedproduct is high in both yield and purity and is applicable to large-scale production.

A condensation copolymerization reaction between bis-phenol A and p-bis-(chlorodifluoro-methyl)benzene has been carried out to form a novel fluoropolymer that has excellent thermal and solubility properties. It is proposed that this polymerization reaction occurs via an unprecedented SRN1 mechanism. This demonstration of the use of SRN1 chemistry for condensation polymerizations of fluorinated monomers creates the opportunity for preparation of new fluoropolymers which are otherwise inaccessible.
