  Radical polyaddition reaction of bis(α-trifluoromethyl-β,β-difluorovinyl) 2,3,5,6-tetrafluoroterephthalate

  摘要：

  To develop the radical polyaddition of bisperfluoroisopropenyl esters to preparation of polymers bearing higher fluorine content, the polyaddition reactivity of bis(alpha-trifluoromethyl-beta,beta-difluorovinyl) 2,3,5,6-tetrafluoroterephthalate [CF2=C(CF3)OCOC6F4COOC(CF3)=CF2] (TFT) with 1,4-dioxane (DOX) and diethoxydimethylsilane (DEOMS) were described. The results of the model reactions of 2-pentafluor-obenzoxypentafluoropropene [CF2=C(CF3)OCOC6F5] (PFBP) with THF, DOX and DEOMS showed that the reactions took place almost quantitatively and the main products were mono-addition compound for THF and di-addition compounds for DOX and DEOMS, respectively. The polyaddition of TFT with DOX or DEOMS yielded corresponding polymers of about I x 104 as a molecular weight bearing unimodal molecular weight distribution by the initiation of peroxides such as benzoyl peroxide and di-tert-butyl peroxide. TFT showed the slightly higher reactivity compared to that of non-fluorinated analogue, bis(a-trifluoromethyl-P,P-difluorovinyl) terephthalate (BFP), by the results of ternary polyaddition of TFT/BFP/DOX system. Polymers bearing TFT moiety showed the higher thermostability and contact angle. (C) 2003 Elsevier B.V. All rights reserved.
