    摘要： 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.
