<p>PROBLEM TO BE SOLVED: To provide a heat-resisting container with little deformation when it is soaked in hot water. SOLUTION: This is a synthetic resin heat-resisting container with an opening formed of resin composition containing aromatic vinyl polymer 40-97 wt.%, polyolefin resin 3-60 wt.% and aromatic vinyl-diene block copolymer and/or hydrogenated aromatic vinyl-diene block copolymer 1-30% wt.%. The ratio (d2/d1) of the maximum container depth d1 and the maximum container depth d2 after the same is soaked in 70 deg.C water for 30 minutes is within 0.9-1.1 range.</p> |
