A process for the production of hollow heat-recoverable articles which comprises deforming a substantially non-cross-linked polymeric material at a temperature below the crystalline melting point or softening point of the material, fusing together parts of the material or a part or parts of the material and at least one other polymeric component to produce the configuration of at least one hollow heat-recoverable article and subsequently cross-linking the substantially non-cross-linked material.

A process for the production of a hollow heat-recoverable article, the steps comprising: deforming a substantially non-cross-linked polymeric material at a temperature below the crystalline melting point or softening point of the material to render the material heat-recoverable primarily in one direction; fusing together parts of the material to one other substantially non-cross-linked polymeric component to produce a hollow heat-recoverable article having a radial axis and a longitudinal axis, said article being heat-recoverable substantially only in a radial sense; and, cross-linking the fused portions of the polymetic material.
