<p>Co-telomer cpds., which are new, and their salts, have formula (I) where A = random polymer residue contg. at least one gp. of formula (II) and at least one gp. different from (II) and having formula (III) B = H or A; m, n = integers, where m + n = integer 3-100 n : m = 99 : 1 to 1 : 99, so that the resulting telomers are water-soluble and m and/or n in A can be identical or different from m and/or n in B; R = H, Me or Et; R1 = -OX; X = H, alkali- or alkaline earth metal. NH4 or an amine gp.; R2 = H, Me or -CO2R5, R5 = H or linear or branched 1-8C alkyl opt. substd. by one OH gp.; R3 = H, linear or branched 1-4C alkyl, HOCH2- or -CO2R6; R6 = H, a gp. of formula (IV), a gp. of formula -(CH2-CH(R9)O)zH; or linear or branched 1-8C alkyl opt. substd. by -OH or -SO3M; R9 = H, Me or Ph; z = integer 1-20; M = H or an alkali- or alkaline earth metal atom; R4 = -CO2R6, linear or branched 1-8C alkyl opt. substd. by 1 or 2 -COOH gps., PH, acetyl, HOCH2-, acetomethyl-, -SO3M, -CH2SO3M or -PO2M2, -CONR7R8 or -N(R10)COCH3; R7, R8 each = H, linear or branched 1-8C alkyl, HOCH2-, -CH(OH)CO2M, -C(CH3)2-CH2SO3M or -C(CH3)2CH2PO3M2; R10 = H or linear or branched 1-4C alkyl.</p> |
