    摘要： The invention relates to a process for preparing crosslinkable polymers containing silane groups having at least one hydrolyzable radical by free-radical-initiated grafting of the base polymers with an olefinically unsaturated silane having at least one hydrolyzable radical, wherein the grafting is carried out in the presence of (a) an alkylsilane of the formula I, R1(SiR2nX3−n)m,  (I)  where R1 is a monovalent hydrocarbon radical having from 1 to 33 carbon atoms or a divalent hydrocarbon radical having from 4 to 24 carbon atoms, R2 is a hydrocarbon radical having from 1 to 10 carbon atoms, X are identical or different hydrolyzable radicals, n is 0, 1 or 2 and m is 1 or 2 and/or (b) a fluoroalkylsilane of the formula R3xSiR4yXz,  (II)  where R3 is a fluoroalkyl radical, R4 is an alkyl radical and X is a hydrolyzable radical, x is an integer from 1 to 3, y is 0, 1 or 2 and z is an integer from 1 to 3,  with the proviso that the sum x+y+z=4.
