Claim:
A synthetic polymer comprising monomer units represented by the formula: wherein R is —(CR 3 R 4 ) a — or —CR 3 ═CR 4 —; R 1 is hydrogen; saturated or unsaturated alkyl, aryl, alkylaryl or alkyl ether having from 1 to 20 carbon atoms; or —(R 5 ) q O((CR 3 R 4 ) r O) s —R 6 ; each R 2 is independently a divalent, linear or branched, substituted or unsubstituted alkylene, alkenylene, alkynylene, arylene, alkylarylene, divalent alkyl ether or aryl ether moiety having from 1 to 30 carbon atoms; —(R 5 ) q O((CR 3 R 4 ) r O) s (R 5 ) q —; or —(R 5 ) q CO 2 ((CR 3 R 4 ) r O) s CO(R 5 ) q —; R 3 and R 4 are each independently, hydrogen or linear or branched, substituted or unsubstituted alkyl having from 1 to 10 carbon atoms, R 5 is independently linear or branched lower alkylene or lower alkenylene; R 6 is independently linear or branched, substituted or unsubstituted, saturated or unsaturated lower alkyl; the aromatic ring has from zero to four Z 1 substituents, each of which is independently selected from the group consisting of halide, lower alkyl, alkoxy, nitro, alkyl ether, a protected hydroxyl group, a protected amino group and a protected carboxylic acid group; Y is a is 0 to 10; each q is independently 1 to 4; each r is independently 1 to 4; and each s is independently 1 to 5000.
