Patent ID: 7863406

Claim:
A polymer having the structural formula: wherein R 1 is selected from the group consisting of (C 2 -C 20 ) alkylene and (C 2 -C 20 ) alkenylene; R 3 is selected from the group consisting of hydrogen, (C 1 -C 6 ) alkyl, (C 2 -C 6 ) alkenyl, (C 2 -C 6 ) alkynyl and (C 6 -C 10 ) aryl (C 1 -C 6 ) alkyl; and R 4 is selected from the group consisting of (C 2 -C 20 ) alkylene,(C 2 -C 20 ) alkenylene, and ((CH 2 ) r O) q -(C 2 -C 20 ) alkylene where r is 2 or 3 and q ranges from 1 to 4, and where at least one of R 1 and R 4 comprises a radical selected from the group consisting of (C 2 -C 20 ) alkenylene; and n ranges from about 5 to about 150 attached via double bond functionality to non-biologic drug or bioactive agent selected from the group consisting of anti-inflammatory agents, antiproliferative agents, biologics, protein, cytokines, oligonucleotides, genes, carbohydrates and hormones.
