  • METHOD FOR PREPARING FUNCTIONALIZED POLYORGANOSILOXANE RESINS BY REDISTRIBUTION IN THE PRESENCE OF AT LEAST ONE TRIFLIC ACID DERIVATIVE
    Publication number: 20080255322
    Abstract: The present invention relates to a process for preparing functionalized polyorganosiloxane (POS) resins comprising units M: (R3SiO1/2) Q: (SiO4/2) and M?: (YaR3?aSiO1/2) and optionally D: (R2SiO2/2) and/or D?: (RYSiO2/2) and T: (RSiO3/2) and/or T?: (YSiO3/2), with, in these units: R=C1-C10 alkyl or a C8-C12 aryl and Y a functional group (e.g.: Si—H), by redistribution of POS resins using POSf bearing functional units M? and/or D? and/or in the presence of an acid catalyst of the trifluoromethane-sulfonimide (TFSI) type. The present invention also relates to the aforementioned catalyst system.

  • Process for preparing functionalized polyorganosiloxane resins by redistribution in the presence of triflic acid and/or of at least one derivative thereof and of a nonbasic inert filler
    Publication number: 20080255292
    Abstract: The invention provides a method for preparing functionalized polyorganosiloxane resins (POS) comprising units M: (R3SiO1/2), Q: (SiO4/2) and M?: (YaR3-aSiO1/2) and optionally D: (R2SiO2/2) and/or D?: (RYSiO2/2) and T: (RSiO3/2) and/or T?: (YSiO3/2), wherein in said units R is C1-C10 alkyl or C8-C12 aryl and Y is a functional group (such as Si—H), by redistributing POS resins, using POSf bearing functional groups M? and/or D? and/or in the presence of an acid catalyst such as triflic acid or one of its derivatives and a non-basic inert filler: carbon black, diatomaceous earth, zeolite or acid or neutral oxide (Al2O3, Na2O, TiO2, MgO, silica). The invention also provides said catalyst system.
