A process for the preparation of a plastic organopolysiloxane composition which can be stored in the absence of water and which is convertable even at room temperature into rubber-elastic compositions by the action of water or atmospheric moisture, comprising mixing a hydroxyl-terminated poly-diorganopolysiloxane with about 0.1-15% by weight of the total mixture of a substance of the formula RWROZSi[NR'''R'RnSi(OR)3-n]4-m wherein R is an alkyl radical having 1-4 C atoms, R' is a divalent alkylene radical having 1-6 C atoms or a unit of the formula -(CH2)3NH(CH2)2- or -(CH2)2-NH(CH2)2NH(CH2)2-, R''' is an alkyl radical having 1-4 C atoms, RWRO2Si or hydrogen, n is 0, 1 or 2, and m=W+Z=0, 1, 2 or 3, or a partial hydrolysis product thereof as a crosslinking agent. |
