This paper is the continuation of a previous paper (A.L. Yarin, J. Non-Newtonian Fluid Mech., 37 (1990) 113-138 and reports a theoretical study of the scission (mechanical degradation caused by the flow of polymeric liquids) of macromolecules within the framework of micromechanical models of dilute and concentrated systems. The theoretical analysis of the degradation in flows of dilute polymer solutions is presented in Section 2. Section 3 deals with the development of the theory of scission in flows of concentrated polymeric systems. The proposed equations describe the mutual influence of mechanical degradation, rheological behaviour and flow of polymeric liquids.
