Patent ID: 8106146

Claim:
A polymer comprising: a polymer including two or more repeat units selected from a repeat unit of the formula (Formula VI): wherein each POE T and POE 2 , independently, is represented by the formula: or the formula: wherein: each R 9 , R 10 , and R 17 independently represents hydrogen or an organic group; each R 11 , R 13 , R 15 , and R 16 independently represents an organic group; R 18 represents oxygen or an organic group and p =0 or 1; n =0 or 1; each R 11 can optionally be joined with R 13 to form one or more rings; geminal R 15 and R 16 groups can optionally be joined to each other to form rings; each A, optionally, is —C(R 1 )(R 2 )—(C(R 5 ) 2 ) r ,—C(R 3 )(R 4 )—,—Ar het —, —Ar 1 C(R 6 )(R 7 )—, a group of the formula (Formula III) —Ar 2 —C(R 8 ) 2 —Ar 2 —(B) m —, —C(═O)—, —(C═O)—R—(C═O)—, or combinations thereof; R is an organic group; each R 1 , R 2 , R 3 , R 4 , and R 5 independently represents hydrogen or an organic group, r is 0 to 20, and one or more of R 1 , R 2 , R 3 , R 4 , and R 5 can optionally be joined with one another to form one or more rings; Ar het represents a 1,2-heteroarylene group; Ar 1 represents a 1,2- or a 1,3-arylene group, or a 1,2- or a 1,3-heteroarylene group, R 6 and R 7 independently represent hydrogen or an organic group, and R 6 and/or R 7 can optionally be joined with each other or with the Ar 1 group to form one or more rings; each Ar 2 independently represents an arylene group, each R 8 independently represents an organic group, B represents an aromatic-containing organic group having a linking oxygen attached to the aromatic ring, and m =0 or 1; each x is 1 to about 200; each y, if present, is 0 to about 200; x +y is from 2 to about 400; and each Z is a therapeutic agent containing at least one phenoxy residue and at least one hydroxyl residue or at least a second phenoxy residue.
