Abstract (en)

[origin: WO9618667A2] The present invention relates to linear, cyclic or branched polyorganosiloxanes having per molecule at least 3 siloxyl patterns of which at least one is a functional pattern having formula (I), wherein R<1> is a C1-C4 alkyl radical or phenyl; X is a monovalent group containing one or a plurality of cyclic amines having formula (II), wherein R is a hydrocarbon group, U is -O- or -NR'- with R' being H or a hydrocarbon group, Z is a tetraalkyl-2,2,6,6 piperidinyl group, x = 0 and 1; y = 0, 1 and 2; z = 1, 2 and 3; y +z = 3; and a is 0, 1 and 2. The present invention also relates to the utilization of such polyorganosiloxanes in polymers to improve particularly their photostabilization.
