摘要：

The aim of this paper is to relate recoverable strains in shear and elongation to the relaxation time spectrum of the melt. For that purpose, the state of stress for a given strain history is calculated on the basis of a single integral constitutive equation with strain-dependent memory function as proposed by Wagner (cf. Refs. 2 and 3). In the limit of small shear or elongation rates, this reduces to Lodge's rubberlike liquid constitutive equation (cf. Ref. 4).
