    摘要： A multi-component crosslinkable composition includes at least one component (K1) and one component (K2). Component (K1) contains organosilicon compounds (A1) selected from compounds (A1a) of formula (Ia), the formula (Ia) being Y1—[B1—CR22—SiRa(OR1)3-a]x, and compounds (A1b) of formula (Ib), the formula (Ib) being Y2—[B2—(CR42)b—Si(OR3)3]y. Component (K2), based in each case on 100 parts by weight of compounds (A1) in component (K1), includes at least 0.05 parts by weight of water and 10 to 1000 parts by weight of a component (A2) selected from compounds (A2a) of formula (IIa), the formula (IIa) being Y3—B3—CR72—SiR5c(OR6)3-c, and compounds (A2b) of formula (IIb), the formula (IIb) being Y4—[B4—(CR102)e—SiR8d(OR9)3-d]z.

    摘要： A process for preparing silane-terminated polymers (SP) of the formula (I), Y—[O—C(═O)—NH—(CR12)b—SiRa(OR2)3-a]x  (I), includes in a 1st process step at least one polymer (OHP) of the formula (II), Y—[OH]x  (II), being reacted with at least one isocyanate-functional silane (IS) of the formula (III), O═C═N—(CR12)b—SiRa(OR2)3-a  (III), with the proviso that the isocyanate-functional silanes (IS) are used in an amount such that there are at least 1.05 isocyanate groups in the silanes (IS) to each hydroxyl group in the compounds (OHP). Subsequently, in a 2nd process step, the unreacted isocyanate groups of the silanes (IS) are reacted, in the reaction mixture obtained in the 1st process step, with at least one alcohol (A) of the formula (IV), R3OH  (IV) Subsequently, in a 3rd process step, the reaction mixture obtained in the 2nd process step is passed through an evaporation unit (VD).
