摘要：

1,3-Bis(trimethylsilylmercapto)benzene was condensed with 4,4'-difluorodiphenylsulfone, 2,6-difluorobenzonitrile or 2,6-difluoropyridine in bulk. A second series of polycondensations was conducted with activated dichloroaromatics in N-methylpyrrolidone. The latter method gave the higher molecular weights (weight-average molecular weights up to approx. 35000). All polysulfides are amorphous materials with glass-transition temperatures in the range of 105-155-degrees-C.
