<p>An ionomer composition which comprises an ionomer crosslinked with a polyamide chain and composed of 85 to 99 parts by weight of an ionomer component wherein at least part of carboxyl groups of the ethylene-unsaturated carboxylic acid copolymer are neutralized with a metallic cation and 15 to 1 part by weight of a polyamide oligomer component having primary amino groups on both ends, and which has an MFR value (at 190°C, under a load of 2160 g) of 0.001 to 30 dg/min. This composition shows excellent mechanical strengths at high temperatures, hot oil resistance, deep drawing properties and thermal rupture resistance and is excellent in moldability, transparency and surface gloss.</p> |
