Abstract:
A polyadduct which is formed from nonlinear-optically active terpolymer of the general formula 1R1, R2, R3 are identical or different from one another and are H, CH3 or halogen; X1, X2, X3 are identical or different from one another and are O or NR4, where R4 is H or a linear or branched C1- to C6- alkyl radical; Y1 is a linear or branched hydrocarbon chain having 2 to 20 carbon atoms, where one or more nonadjacent CH2 groups, with the exception of the CH2 group providing the link to the radical Z, can be replaced by O, S or NR5, where R5 is H or a linear or branched C1- to C6- alkyl radical; Y2 is a linear or branched hydrocarbon chain having 1 to 3 carbon atoms; Y3 is a linear or branched C1- to C20- alkyl radical, a C5- to C7- cycloalkyl radical or a bi- or tricyclic cycloaliphatic radical having up to 18 carbon atoms; Z is a nonlinear-optically active group; and l:m:n=1 . . . 99:1 . . . 99:1 . . . 99, and at least one crosslinking agent based on a carboxyl-functional polyester.
