title: The viscosity law of dendronized linear polymers.
abstract: The intrinsic viscosity [η] of dendronized linear macromolecules dissolved in thermodynamically good solvents depends both on chain length that is contour length L(c) of the backbone of the polymer and on the persistence length l(p). Investigating a set of samples of identical L(c) but differing in the generation number for which data on lp are available, it becomes possible to establish a generalized viscosity law in the form [η] = K(M/M(p))(α) in which M(p) denotes the molar mass of the objects per l(p), M is the total molar mass, K is a constant, and α is the Mark-Howink exponent, which is found to be 0.55.
