Claim:
1. A composition, consisting of: (i) a polymeric carrier; and (ii) a plurality of hydrophobic groups with a covalently linked protective side chain, wherein the hydrophobic group has a first end that is covalently linked to the carrier and a second end that is covalently linked to the protective side chain, wherein each hydrophobic group of the plurality of hydrophobic groups comprises an alkyl group of 8-36 carbons and has a molecular weight between 150 to 1000 Daltons independent of the carrier and protective side chain weights; wherein the protective side chain is polyethylene glycol, polypropylene glycol, a co-polymer of polyethylene glycol and polypropylene glycol, or an alkoxy derivative thereof; wherein the protective side chain has a molecular weight between about 400 and 20,000 Daltons independent of the carrier and hydrophobic group weights; wherein the weight ratio of the protective side chains to the hydrophobic groups is more than 17:1; and wherein the composition is soluble in an aqueous solvent.
