<P>PROBLEM TO BE SOLVED: To provide a composition of polyethylene lining that uses PE basically excellent in moisture barrier properties and chemical stability as a base, and has improved erosion resistance and to provide a lining method. <P>SOLUTION: The composition for lining includes linear low-density polyethylene and a thermoplastic elastomer of a pseudo-crosslinking type which is composed of a hard block including polystyrene and an elastomer block having a polyolefin structure in which the elastomer block undergoes pseudo-crosslinking at a temperature of not higher than the glass transition temperature Tg of the hard block, with the hard block acting as a pseudo-crosslinking point; and the thermoplastic elastomer shows flowability at a temperature of higher than the Tg. <P>COPYRIGHT: (C)2013,JPO&INPIT |
