Claim:
A functionalized triclosan oligomer of formula A or B: R[(CH 2 ) f C(═O)—(Y) a —O—R 1 ] w A; R[—(Y) a —O—R 1 ] w B; wherein: each Y is independently: —OCH 2 C(═O)— (inverse glycolic ester moiety), —OCH(CH 3 )C(═O)— (inverse lactic ester moiety), —OCH 2 CH 2 OCH 2 C(═O)— (inverse dioxanone ester moiety), —OCH 2 CH 2 CH 2 CH 2 CH 2 C(═O)— (inverse caprolactone ester moiety), —O(CH 2 ) y C(═O)—, or —O(CH 2 CH 2 O) z OCH 2 C(═O)—; R is a di-, tri, tetra-, penta- or hexaradical derived from C 1-25 alkyl, aryl, or aryl-(C 1-6 alkyl) 1-3 -, wherein from 1-4 of the CH 2 groups within the alkyl chain are optionally independently replaced by O or S atoms, preferably by O atoms, such that each of said O or S atoms is attached only to carbon atoms in the alkyl chain, with the proviso that the O or S atoms are separated from the di-, tri, tetra-, penta- or hexaradical chain ends by at least one carbon atom and that multiple O or S atoms in the di-, tri, tetra-, penta- or hexaradical chain must be separated from each other by at least two carbon atoms; or R is —[CH 2 CH 2 O—] p —, wherein p is an integer from about 10 to about 50; R 1 is: each a is independently an integer from about 1 to about 8; each f is independently the integer 0 or 1; with the proviso that when f is 0, then R is other than —[CH 2 CH 2 O—] p —; each y and z is independently an integer from about 2 to about 24; w is an integer from about 2 to about 6.
