## Abstract The intrinsic viscosities [ฮท] and viscosity constants of high molar mass poly(acrylonitrileโ__co__โitaconic acid) copolymer in DMF were obtained by the methods of Huggin, Fuoss, Martin and SchulzโBlaschke. The values of [ฮท] by averaging procedures suggested by Sakai were close to those
The mechanical shear degradation of polydisperse polyisobutene and monodisperse polystyrene in oils of different viscosities in the concentration range of 0.1% to 1% was studied using a high-shear concentric cylinder viscometer under laminar and uniform well-defined shear field conditions.

## Abstract **Summary:** Polymer orientation in dilute solutions undergoing shear flow is investigated computationally by means of the Brownian dynamics simulation technique applied to the beadโspring chain model. The dependence of the degree of orientation on the shear intensity is evaluated throu
