Abstract:
1. The reaction product of (A) a polymeric backbone selected from the compounds of the formulas with (B) a chromophore selected from the compounds of formulas wherein T, U and Q independently from each other, represent repeating units of a polymer backbone; X wherein V is straight-chain or branched —C Z is a biradical of formula R R Y is R Y G represents a functional group capable of reacting with the polymeric backbone (A) selected from halide, activated methoxy, hydroxy, tosylate, mesylate, carboxylic acid, carboxylic acid chloride, carboxylic ester, sulfonyl chloride, vinyl sulfone, acrylate, isocyanate, epoxide, anhydride, primary, secondary or tertiary amines and hydroxy; m is a number from 0 to 50000; n is a number from 0 to 50000; and p is a number from 1 to 50000; m and n independently from each other are 0, or 1; wherein the sum of m+n+p≧3; t and u independently from each other are 1, or 2; and with (C) at least one sulfide containing compound of formula wherein X X Z —CON(R 4 )—; —(R 5 )NC(O)—; —CH 2 C(O)N(R 6 )—; —(R 6 )NC(O)CH 2 —; —O—; —S—; —S(O)—; or —S(O) 2 —; R G q, r and s independently from each other are 0 or 1; if s is 0, Z wherein R R R v is a number from 1 to 4; and wherein the —(CH R V is hydrogen; C W is O; S; or N—R R if s is 1, Z wherein the polymeric backbone (A) can be reacted either first with the sulfide containing compound (C) and then with the chromophore (B); or first with the chromophore (B) and then with the sulfide containing compound (C); or the polymeric backbone (A) can be reacted simultaneously with the chromophore (B) and with the sulfide containing compound (C).
