ABSTRACT:
Organo(poly)siloxanes composed of units of the formula [R.sub.a R.sup.1.sub.3-a SiO.sub.1/2 ], [R.sub.b R.sup.1.sub.2-b SiO.sub.2/2 ] and [R.sup.1 SiO.sub.3/2 ], in which R can be the same or different and represents a monovalent organic radical which is free from aliphatic carbon-carbon multiple bonding, R.sup.1 can be the same or different and represents a monovalent organic radical which has at least one aliphatic carbon-carbon multiple bond, a is 0, 1 or 2 and b is 0 or 1.
