Abstract:

The condensations of methylpentafluorophenyldiethoxysilane, methyltetrafluorochlorophenyldiethoxysilane and bispentafluorophenyldiethoxysilane respectively with 1,3-dichlorotetramethyldisiloxane using electrophilic catalysts are described. The results of homo- and co-polycondensation with dimethyldichlorosilane of bisdimethylchlorosilyltetrafluorobenzene and methylpentafluorophenyldichlorosilane are reported. Properties and Tg values of the resultant polymers are also discussed. Author
