## Abstract We have analyzed chain conformations and the existence β or otherwise β of chain overlaps and entanglements in dilute polymer solutions (at concentrations __c__ < __C__^\*^, __c__^\*^ = critical concentration). The fundamental problem of existence of chain overlaps in dilute solutions i

## SYNOPSIS Carbon-13 spin-lattice, spin-spin relaxation times, and NOE values were measured as a function of temperature at two magnetic fields for poly(vinyl chloride) (PVC) in three solvents: chloroform, dioxane, and dimethyl sulfoxide. The relaxation data were interpreted in terms of chain loc
## Abstract **Summary:** Polymer orientation in dilute solutions undergoing shear flow is investigated computationally by means of the Brownian dynamics simulation technique applied to the beadβspring chain model. The dependence of the degree of orientation on the shear intensity is evaluated throu
