Study on isomeric bisphenol F based benzoxazine

Bisphenol F based benzoxazines were synthesized by solution method,using isomeric bisphenol F and para bisphenol F,respectively.The structure,curing behavior and property of the cured products of the two bisphenol F based benzoxazines were investigated by FTIR,1H NMR,GPC,DSC,DMA and TGA.The results showed that the properties of the synthesized benzoxazine were affected by the isomers of bisphenol F.The ring-closed ratio,heat resistance and thermal stability of para bisphenol F based benzoxazine were higher than that of the isomeric bisphenol F based benzoxazine.
