ABSTRACT:
A laminar thermoplastic resin structure comprising a plurality of thermoplastic resin layers is obtained by bonding thermoplastic resin layers with a layer, or layers, of a maleic acid-modified block copolymer of a conjugated diene and an aromatic vinyl monomer interposed therebetween.
The laminar structure thus obtained possesses a high bonding strength at elevated temperatures, and also excellent processability since the bonding layer per se is of thermoplastic nature. Thus, this laminar structure is particularly suitable as a material for use at elevated temperatures, for example, a packaging material for retort sterilization or a pipe for conducting hot fluids.
