Small-angle x-ray scattering from solid solutions of different molecular weight fractions of partially brominated polystyrene in polystyrene has been studied. The results of this study indicate that polymer chains in bulk have a radius of gyration proportional to the square root of molecular weight,

The polymerization of macromonomers provides polymers of extremely high branching density with regular branch length, branching number and branching interval. The intrinsic shape and size of these polymacromonomers were evaluated by small-angle X-ray scattering. The conformation of the backbone and
## Abstract Smallβangle xβray scattering of poly(Ξ³βmethylβLβglutamate), [Glu(OMe)]~__n__~, in mβcresol and in pyridine was measured to determine the mass per unit length, __M__~__q__~, and the radius of gyration of the cross section, γ__S__γ^1/2^. It was confirmed from the values of __M__~__q__~ th
