Abstract
The present invention proposes a silane and an organopolysiloxane containing a cyclopentenyl radical, characterized in that the silane or the organopolysiloxane has a radical Y of the formula: ##STR1## directly linked to the silicon atom. The silanes according to the invention can be used as coupling and crosslinking agents, in particular in the compositions of acrylic paints. The diorganopolysiloxanes according to the invention can be used as base polymer of a silicone composition which is crosslinkable to an elastomer, in particular by exposure to atmospheric oxygen.
