Abstract:
1. A process for preparing a block copolymer characterized by the general formula (AB) n -Core, or having the structure A-B-A, where A and B are polymeric blocks and Core is a non-polymeric linking core; wherein said block copolymer comprises at least one random block comprised of two or more monomers, wherein at least one of said two or more monomers is hydrophilic and at least one of said two or more monomers is hydrophobic such that an absolute difference in log p between said at least one hydrophobic and hydrophilic monomers is at least about 0.5; and n is 2 or more; and provided that said block copolymer is soluble or miscible in water or alcohol or a combination thereof at a concentration of at least about 20 mg/mL at room temperature, the process comprising polymerizing telechelic polymers of blocks A and B and attaching said telechelic polymers together with covalent bonds.
