摘要： Novel, alkenyloxy-functional organosilicon compounds are described which contain at least one Si-bonded Y radical per molecule having the formula--(CH.sub.2).sub.2 --R.sup.2 --(A--R.sup.3).sub.z --O--CH.dbd.CH--CH.sub.2 --R.sup.4 (I),in which A represents --O--, --S-- or ##STR1## R.sup.2 represents a linear or branched alkylene radical having from 1 to 7 carbon atom(s) per radical or a cycloalkylene radical having from 5 to 7 carbon atoms per radical, R.sup.3 represents a linear or branched alkylene radical having from 2 to 4 carbon atoms per radical, which may be substituted by a hydroxyl group, methoxy group, ethoxy group or trimethylsiloxy group, R.sup.4 represents a hydrogen atom or an alkyl radical having from 1 to 4 carbon atoms(s) per radical, and z is 0, 1, or 2. The alkenyloxy-functional organosilicon compounds are preferably silanes or organopolysiloxanes. The alkenyloxy-functional organopolysiloxanes can be crosslinked, for example, with ultraviolet light. These organopolysiloxanes can also be used for preparing coatings.

摘要： Novel siloxane copolymers are described having an average of at least two alkenyloxy groups of the formula--OCR.sup.2 .dbd.CH.sup.2 CH.sub.3,in which R.sup.2 represents hydrogen or a methyl radical.These siloxane copolymers are prepared by reacting in a first stage, an organic compound (1) containing more than two aliphatic double bonds of the formula OCHR.sup.2 CR.sup.2 =CH.sub.2 where R.sup.2 is the same as above, with an organopolysiloxane (2) having at least one Si-bonded hydrogen atom per molecule in the presence of a catalyst (3) which promotes addition of the Si-bonded hydrogen to an aliphatic double bond and in a second stage heating the siloxane copolymer in the presence of a catalyst (4) which promotes shifting of the terminal double bond to form copolymers having an internal double bond.
