Organopolysiloxane compositions obtained by reacting (a) silanol-terminated linear organopolysiloxanes with (c) chain-extenders of the dialkylaminoalkyl-alkyl-dialkoxy-silane type, (d) deactivators and optionally (b, e, f) plasticisers, alkyltrialkoxysilanes and catalysts. Organopolysiloxane compositions (OPS) obtained by reacting (a) essentially linear organopolysiloxanes with Si-linked hydroxyl groups at both ends, (b) optionally plasticisers, (c) chain-extender(s) of formula (R1)2NC(R6)2-SiR1(OR2)2 (I) and/or their partial hydrolysates, (d) deactivators, (e) optionally silanes of formula R3Si(OR4)3 (II) and (f) optionally catalysts for the reaction of silanes (e) with OH groups. R1, R2, R3 = optionally substituted hydrocarbyl; R6 = H or optionally substituted hydrocarbyl; R4 = optionally substituted hydrocarbyl or a group of formula -CO-R5 or -N=C(R5)2; R5 = as for R2 . Independent claims are also included for (1) a method for the production of OPS by mixing the above components together and allowing them to react (2) condensation-crosslinking materials containing OPS (3) moulded products obtained by crosslinking these materials |
