A proton conducting film includes a polymer having a first part and a second part which are connected by a covalent bond and a plasticizer. The first parts aggregate with each other to form a domain at an operation temperature of the proton conducting film, and the second part crosslinks the domains. The second part has a proton accepting group, and the plasticizer contains a proton donating compound having a pKa of 2.5 or less, and thus the plasticizer penetrates into the second part, and a glass transition temperature of the polymer is lowered compared to when the plasticizer is not included.

A block copolymer is provided. The block copolymer includes a first block including repeat units represented by formula (I), and a second block connected to the first block and including repeat units represented by formula (II) or (III). The disclosure also provides a method for preparing the block copolymer and a thin film structure including the same.

The present invention relates to an aqueous autodeposition composition comprising iron(II) ions, fluoride ions, at least one chain transfer agent and at least one dispersed organic binder component, wherein the organic binder component comprises at least one water-dispersible polymerizable (meth)acrylic acid component; and at least one acrylated mono- or diphosphate ester component.

The present invention describes a method of capturing a fluorinated carbon compound located within a liquid, the method comprising contacting the fluorinated carbon compound with a block copolymer having a backbone comprising a hydrophilic block and a fluoropolyether block, wherein the fluorinated carbon compound binds to and is captured by the block copolymer.

Provided is a composition for emulsion polymerization which includes: an asymmetric compound represented by the following Chemical Formula 1; an aromatic vinyl monomer; and a conjugated diene-based monomer, and a rubber compound prepared from the same.

##STR00001##
