D. Papanagopoulos et A. Dondos, Universal behavior of linear and star-shaped polymers using relations derived from the blob theory and two parameter theory, EUR POLYM J, 37(5), 2001, pp. 989-993
The viscometric expansion factor of linear and star-shaped polymers is rela
ted to the number of blobs of their chains. It was found that this relation
is universal for these two different polymer architectures. Using samples
of linear and star-shaped polymers we have also established a second univer
sal law relating the hydrodynamic volume of the chains to their critical ov
