Abstract:
1. A block copolymer comprising a methoxyethyl methacrylate (MOEMA) midblock and A and B end blocks, the copolymer having a general formula of A-[MOEMA] n -B, wherein n is a positive integer from 1 to about 100,000, wherein the A block is formed from first monomer(s) and the B block is formed from second monomer(s), or the A block is formed from second monomer(s) and the B block is formed from first monomer(s), wherein the first monomer is selected from fluorinated methacrylate monomer(s), fluorinated acrylate monomer(s), 2-phenylacrylate, 2-phenylacrylamide, 1H,1H,2H,2H-heptadecafluorodecyl methacrylate, and 1H,1H,3H-hexafluorobutyl methacrylate, wherein the second monomer is selected from vinyl monomers having pendant groups selected from the group consisting of pyrrolidone group(s), carboxylic acid group(s), sulfone group(s), sulfonic acid group(s), amino group(s), alkoxy group(s), amide group(s), acetate group(s), poly(ethylene glycol) group(s), poly(propylene glycol) group(s), poly(tetramethylene glycol) group(s), poly(alkylene oxide) group(s), hydroxyl group(s), or a substituent that bears a charge or any of pyrrolidone group(s), carboxylic acid group(s), sulfone group(s), sulfonic acid group(s), amino group(s), alkoxy group(s), amide group(s), acetate group(s), poly(ethylene glycol) group(s), poly(propylene glycol) group(s), poly(tetramethylene glycol) group(s), poly(alkylene oxide) group(s), and hydroxyl group(s), and wherein the block copolymer is a phase separate amphiphilic copolymer.
