## Abstract Equations for the mean square radius of gyration and the hydrodynamic radius for jointed stars (dumbbells) and Hβcombs are derived, based on random flight statistics for each subchain. Comparision with literature data on computer simulations and experimental data for Hβcombs show good a

We built up star-branched polymers, whose morphology is fully determined by diffusion, with p ΒΌ 1; 3; 6 and 12 branches with a total of 30,000 monomer units. We investigated their structural properties by calculating the monomer-monomer correlation functions. A detailed finite size scaling analysis
Abatract--Acetone solutions of a cellulose diacetate fraction were studied by viscosity and light scattering methods over the range 12.6-50.3:. The temperature dependences of the limiting viscosity number [~/], the mean-square radius of gyration , and the second virial coefficient A2 were determined
