<p>Disclosed herein are a heat-resistant laminate comprising a first layer, as one of the outer layers thereof, made of a polymer of propylene or a polyamide; a seventh layer, as the other outer layer thereof, made of a polyolefin or a polyamide; a fourth layer, as a gas-barrier layer, made of a polymer of vinylidene chloride; a second layer and a sixth layer, as adhesive layers (A), made of a modified polyolefin or a mixture of not less than 90% by weight of the modified polyolefin and not more than 10% by weight of a copolymer of ethylene and an acrylic ester or a modified copolymer of ethylene and an acrylic ester and respectively directly jointed to the first layer and the seventh layer; a third layer and a fifth layer, as adhesive layers (B), made of a mixture of 10 to 30% by weight of a modified polyolefin and 90 to 70% by weight of a copolymer of ethylene and an acrylic ester or a modified copolymer of ethylene and an acrylic ester and respectively disposed between the second layer and the fourth layer, and between the fourth layer and the sixth layer and respectively directly jointed to the gas-barrier layer and the adhesive layers (A), and a process for preparing the same.</p> |
