Heat-resistant liner-provided vessel closure and process for preparation thereof
 Disclosed is a vessel closure having a liner formed from a composition comprising (i) a hydrogenated styrene/butadiene block copolymer having a melt index smaller than 0.1 g/10 min as measured at a temperature of 200.degree. C. under a load of 5 kg, (ii) liquid paraffin and (iii) a propylene resin. In this liner, the compression permanent strain and permanent elongation under high temperature conditions are extremely small, and therefore, even if a divergence is produced between the liner and the mouth portion of a vessel by thermal deformation or thermal shrinkage, a good sealing property can be maintained.
