ABSTRACT:
Organopolysiloxanes, which terminally, laterally or both have at least one group of the formula ##STR1## well as at least one acrylate group, linked over a bridge element to this group, is obtained by hydrosilylation of organopolysiloxanes with at least one SiH group by compounds, which have at least two acrylate groups, in equimolar amounts at a temperature of 60.degree. to 130.degree. C. in presence of rhodium catalysts. The rhodium catalysts cause a 1,2 addition to take place during the addition reaction between polyacrylates and hydrogen siloxanes.
