The invention relates to crosslinkable compositions based on organosilicon compounds and having controllable modulus, to a process for their preparation and to their use, said compositions comprisingn (a) polymers of the formulan nX n R 3-n Si-A-SiR 2 —(CH 2 ) 3 NHY (I)n (b) polymers of the structuren nX 1 k R 5 3-k Si-A 1 -SiX 1 k R 5 3-k (II)n (c) optionally, silanes of the formulan nR 6 m SiX 2 4-m (III)n nand/or partial hydrolyzates thereof, andn (d) optionally, silanes of the formulan nR 4 o SiR 7 p X 3 4-o-p (IV)n nand/or partial hydrolyzates thereof,n nwhere X, X 1 and X 3 are OH or a hydrolyzable group, R, R 4 , R 5 , and R 7 are hydrocarbyl groups, and A is a divalent linking group. |
