Abstract:
1. A polymer having the formula: wherein: A are poly(hydroxyacid) or poly(hydroxy-alkanoate) blocks; B are blocks of a biologically compatible polymer; X is a linking moiety; and n is an integer between 2 and 700; wherein the linking moiety is derived from at least one of or any combination of oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, brassylic acid, dodecane-1,12-dicarboxylic acid, tridecane-1,13-dicarboxylic acid, thapsic acid, fumaric acid, maleic acid, and 1,3-acetonedicarboxylic acid; wherein the biologically compatible polymer is poly(L-lysine)-graft-co-poly(ethylene glycol; and wherein the poly(hydroxyacid) or poly(hydroxy-alkanoate) is one of poly(lactide-co-glycolide); poly(L-lactide); poly(D-lactide); poly(D,L-lactide); poly(L-lactide-co-glycolide); poly(D,L-lactide-co-glycolide); poly(L-lactide-co-caprolactone); poly(D,L-lactide-co-caprolactone); poly(L-lactide-co-D,L-lactide); poly(L-lactide-co-trimethylene carbonate); poly(D,L-lactide-co-trimethylene carbonate); poly(L-lactic acid); poly(D-lactic acid); poly(D,L-lactic acid); or a combination thereof.
