The present invention provides a coating composition, comprising a siloxane group-containing polymer (A) and a crosslinking agent (B), wherein the siloxane group-containing polymer (A) is a block copolymer comprising an A block and a B block, and containing, in the A block, at least a structural unit derived from a siloxane group-containing vinyl monomer (a) and containing, in the B block, a structural unit derived from a hydroxyl group-containing vinyl monomer (b) and, as necessary, a structural unit derived from another vinyl monomer (c) copolymerizable with the vinyl monomers (a) and (b), and is a copolymer having a molecular weight distribution (Mw/Mn) of 2.0 or less and polymerized by living radical polymerization.

Nanopore devices including barriers using polymers with end groups, and methods of making the same, are provided herein. In some examples, a barrier between first and second fluids is provided. The barrier may be suspended by a barrier support defining an aperture. The barrier may include one or more layers suspended across the aperture and including molecules of a block copolymer. Each molecule of the block copolymer may include one or more hydrophilic blocks having an approximate length A and one or more hydrophilic blocks having an approximate length B. The hydrophilic blocks may form outer surfaces of the barrier and the hydrophobic blocks being located within the barrier. End groups may be coupled to ends of the hydrophilic blocks that form outer surfaces of the barrier. The end groups may have a different hydrophilicity than the hydrophilic blocks.

The present invention relates to a water-soluble co-polyester polymer. The polymer of the present invention is used for inline coating of BOPET film manufacturing, coating of BOPET film used as primer for vacuum metallization and surface coating of Aluminum sheets.
