Abstract
The invention relates to an adhesive comprising a polymer having the following features: PA1 a polymeric backbone, PA1 alkyl, aryl and/or alkenyl groups attached to the backbone by way of ester linkages, PA1 alkyl and/or aryl spacer groups attached to the backbone by way of ester linkages, PA1 an open-chain and/or cyclic silicone group and/or silane group is attached to the spacer by means of an Si--C bond, PA1 an ethylene group is attached to the silicone and/or silane group by means of an Si--C bond, PA1 the ethylene group in turn is connected to a second silicone group which comprises M, D, T and/or Q silicone units and comprises at least one vinyl group attached to Si. The adhesive of the invention is stable even under moist conditions and ensures good promotion of adhesion between a polymer and an organosilicon elastomer.
