Zusammenfassung:Crosslinkable compsns. (I) are claimed, based on (a) alkenyloxy-functional organo-polysiloxanes contg. Si-linked gps. Y of formula -(CH2)2-R1-(A-R2)z-O-R3-CH=CH2, (b) organo-polysiloxanes with Si-H gps. and (c) a catalyst for the addn. reaction between Si-H and aliphatic double bonds; A = -O-, -S- or -COO-; R1 = 1-7C linear or branched alkylene or 5-7C cycloalkylene; R2 = 2-4C linear or branched alkylene, opt. substd. with OH, OMe, OEt, or OSiMe3; R3 = 1-7C linear or branched alkylene; z = 0, 1 or 2.
