Patent ID: 8680362

Claim:
A substrate coated with a block copolymer, wherein the substrate is selected from the group consisting of woven webs, nonwoven webs, films, and laminates thereof, and wherein the block copolymer is obtainable by the process of: (i) preparing a sequence of soft block(s) (A) and hard blocks (B), the sequence comprising at least three blocks being at least a first soft block, a first hard block and a second hard block wherein the first soft block is sandwiched between the first and second hard blocks (B), wherein the first soft block has a number average molecular weight of about 20,000 to about 200,000 g/mol, and wherein each of the at least two hard blocks has a number average molecular weight of about 4,000 to about 20,000 g/mol; and (ii) combining the sequence of soft block(s) and hard blocks with a hydrophilic block (C), or combining the sequence of soft block(s) and hard blocks with a hydrophilic block precursor and subsequently transforming the hydrophilic block precursor into the hydrophilic block (C).
