Beschreibung
Zusammenfassung:	A (meth)acrylate ester-modified organopolysiloxane composition, which is composed of several fractions of equilibrated (meth)acrylate ester-modified organopolysiloxanes that differ in the average number of silicon atoms in the mixture of molecules, is disclosed which contains 60 to 95% by weight of a modified organopolysiloxane A having, on the average, 5 to 50 silicon atoms and 5 to 40% by weight of a modified organopolysiloxane B having, on the average, at least 50 silicon atoms, with the proviso that the number of silicon atoms in the average molecule of the modified organopolysiloxane B is at least twice as large as the number of silicon atoms in the average molecule of the modified organopolysiloxane A. The organopolysiloxane mixtures have improved abhesive properties.
