HYDROPHILIC POLYMER, METHOD OF PREPARING THE SAME, AND LITHIUM SECONDARY BATTERY CONTAINING THE HYDROPHILIC POLYMER

The present disclosure relates to a hydrophilic polymer and a method for preparing the same. The hydrophilic polymer is characterized in that it is a copolymer of a conjugated diene, a monoolefin and a hydrophilic monomer represented by Formula I. In the Formula I, X, Xand Xare each independently selected from hydrogen atoms, or a linear or branched alkyl with 1-4 carbon atoms. At least one of R, Rand Ris hydrophilic group; and the others are each independently selected from hydrogen atoms or, an alkyl or alkoxy with 1-4 carbon atoms.
