ABSTRACT:
This invention relates generally to multiple-layered thermoplastic structures. More specifically, it is concerned with a hollow multiple-layered container, preferably formed by co-extruding or co-injecting a first chemically resistant and non-contaminating inner layer and a second structurally reinforcing outer layer into a blow mold, together with a third layer comprising a copolymer blend and functioning as a tie-layer to bond said first layer and said second layer. The hollow multiple-layered container is used for the storage of high purity and highly reactive chemicals.
